Dasher, I like a lot of your ideas, but I think I'd go with "New Avengers" over "Avengers West Coast" as the title.
Except the New Avengers have been renamed Defenders while Hulk and Doctor Strange have jumped ship to Avengers. I feel like West Coast Avengers would be Iron Man's team while Captain America would take the New York team and in the comics, the official Avengers team for New York State is Mighty Avengers. Everyone else shifts between teams.
But thanks for liking my ideas.
Also, I'd set up sequels for Guardians, Iron Man, Hulk, Captain Marvel, Black Panther, Captain America and Thor like this and then cap them off with Avengers
Phase 4
Iron Man: Armor Wars (Ezekiel Stane on orders from Mandarin leaks the blueprints to Tony's armor onto the internet while bankrupting Stark Industries with the help of Ghost and Spymaster while Tony battles alcoholism.)
Hulk: Revenge of the Leader (Leader has escaped SHIELD custody and now seeks to build an army of Gamma Beasts to take over the world including Madman, Half-Life and Flux. Rick Jones and Marlo Chandler team up with Hulk. The Joe Fixit Persona comes about and Jen Walters becomes She-Hulk.)
Captain America: Fallen Son (Crossbones, Doctor Faustus and Sinthia Schmidt as villains. Cap dies in the first five minutes and Winter Soldier and Falcon set off to uncover the conspiracy.)
Thor: Descent Into Hel (Hela and Ymir as villains. Thor defeats Ymir but Hela won't free the souls of Asgard's dead, nor will she even release Captain America, leaving Thor with no reward for his efforts.)
Black Panther: Rebellion (Killmonger and Man-Ape stage a terror campaign against Wakanda over violations of the rights of indigenous people)
Captain Marvel: War of the Marvels (Moonstone would be the villain who usurps Carol's identity)
Guardians of the Galaxy: Celestial Madonna (Mantis and Moondragon join the Guardians)
Inhumans: The Korvac Saga (If you don't know this story, you fail)
Doctor Strange: Sorceror Supreme (Doctor Strange is hired as a paranormal investigator to look into a strange Satanic cult who worship Shuma Gorath and may be guilty of human sacrifice. What Strange encounters is the most horrifying aspects of humanity along with the most depraved of cosmic horrors)
Thunderbolts: Justice Like Lightning!... Hail Hydra; A secret HYDRA plot is afoot led by Baron Helmut Zemo who seeks to avenge his father's death at the hands of either Nick Fury or Peggy Carter of SHIELD and the way he's going to accomplish HYDRA's world domination is through public relations! Watch as he assembles Ghost, Taskmaster, Sentry, Blizzard, Moonstone and Songbird into a team dedicated to saving the world better than the Avengers ever could. The catch is that the Tunderbolts are fighting Leviathan, the same HYDRA splinter faction that allied itself with the Soviet Bloc during the Cold War that Zemo's father founded!)
Ghost Rider (Johnny Blaze makes a pact with a demon and finds himself possessed by a fallen angel that demands the blood of sinners and wants to track down a serial killer called Scarecrow. Blaze doens't want blood on his hands but Zarathos overtakes Blaze as his dominant persona.)
Mighty Avengers: Atlantis Attacks (Namor attempts to avenge the pollution of the world's oceans by flooding Wakanda. Captain America - Now James Barnes - and Black Panther need to stop Namor before he causes any more damage.)
West Coast Avengers: Kang Dynasty (Kang manages to take over the world. Iron Man needs to dethrone him. The catch is that after defeating Kang, he's created a present where Justin Hammer is the Director of SHIELD!)
Phase 5
Captain America: Reborn (Crossbones and Sinthia Schmidt are the villains yet again after the defeat of Doctor Faustus and National Force. This time around, The Grand Director has stepped up to the plate as Captain America and the army has recreated the super soldier serum and used it on John Walker to be the new Captain America. The original frozen corpse of Steve Rogers from which the Cap we knew was cloned from is about to fall into the Grand Director's hands and he's ready to christen himself the true Captain America just as he was back in the 1950s. Worse yet, the man calling the shots for US Agent is Justin Hammer who's taken control of SHIELD. Steve is cloned yet again from his mummified corpse but with all his memories of his past life intact.)
Iron Man: World's Most Wanted (Justin Hammer deems Tony Stark a threat to national security and demands that Tony Stark become a prisoner of SHIELD to construct weapons for them. Tony refuses and a bounty hunter named Whitney Frost with a crush on Tony is scarred in Tony's battle with SHIELD and becomes a crazed, lovesick stalker who not only wants to imprison Tony but believe that he'll love her if she only kills Pepper. The film ends with Iron man surrendering and allowing the West Coast Avengers to operate under SHIELD supervision which was precisely the world he was fighting for in Civil War, he just wasn't fighting for a world where Justin Hammer was his boss.)
Doctor Strange: Book of Chthon (Doctor Strange learns of a tone of immensely powerful black magick which cannot be allowed to fall into the wrong hands. The question is, can Doctor Strange learn and use the secrets contained within or will Chthon's dark powers use him?)
Hulk: Code Red (General Ross becomes the Red Hulk after Justin Hammer demands that Hulk be apprehended. Hulk instead forms a group of armored vigilantes dedicated to justice to fight by his side named Pantheon while Red Hulk forms the Gamma Corps. Hulk marries Betty at the beginning of the film in a double marriage while Marlo and Rick also tie the knot. Amadeus Cho joins the cast as well. Hulk becomes The Professor as his default personality and will probably not change forms much in the future.)
Ghost Rider: Rose of Hell (After Zarathos and Blaze have made peace with one another, Mephisto's son Blackheard doesn't feel that there was enough of a bargain made on Blaze's part and demands that Blaze suffer as per the terms of the pact he made. Blackheart murder's Blaze's girlfriend and turns her into the undead Black Rose.)
Thunderbolts: Dark Avengers (The Thunderbolts have managed to infiltrate SHIELD... except they were invited to replace the Avengers by Justin Hammer. Things have just gotten awkward where the Thunderbolts have now managed to get their revenge without raising a finger despite being HYDRA agents!)
Thor: The Ballad of Beta Ray Bill. (Thor sets off across space and does battle with Ego, The Living Planet. It's mostly about Beta Ray Bill becoming a worthy successor and Ego would just be a plot device with limited screen time.)
Guardians of the Galaxy: The Kree-Skrull War (If you don't know this story, you fail at life.)
Captain Marvel: Call of the Sentry (Carol gained the power of a binary star system from her future self while fighting Kang but can she handle a man with the power of one million exploding suns who Justin Hammer calls upon to replace her within the Avengers?)
Black Panther: Enemy of the State (Red Hulk leads the United States Army on an invasion of Wakanda based on orders from Justin Hammer. Black Panther's own adopted brother betrays him.)
Inhumans 3 (something with Maelstrom)
West Coast Avengers: Evolutionary War (The High Evolutionary seeks to uplift humanity after Thanos' terrigen mists only did so for a fragment of the pupulation. The catch is that a world where everyone has super powers leads to a world where everybody is a walking weapon of mass destruction!)
Mighty Avengers: Seige (Asgard has returned. The problem is that it's returned over Earth and Justin Hammer wants to raid it. Baron Zemo shows his true colors and betrays everyone, including burning the last surviving photographs of Captain America with Peggy Carter in SHIELD headquarters. Captain America has reassembled the Mighty Avengers, the West Coast Avengers rebel against SHIELD, The Thunderbolts have taken their revenge on everyone and Odin declares war on Earth with Thor forced to choose sides. It ends with Asgard and Earth at peace. Justin Hammer in custody, the Thunderbolts as outlaws and Tony Stark as Director of SHIELD.
Phase 6
Captain Marvel: Ascension (Ghazi Rashid gains control of a world destroying super weapon)
Guardians of the Galaxy/Inhumans: War of Kings (If Marvel doesn't have rights to the Shi'Ar by this point, I'll be astounded)
Iron Man: The Future (The Mandarin's vengeance is complete. With the power of a dead celestial to release Extremis across the Earth, Iron Man must join forces with Zeke Stane to break out of the laboratories of Prometheus Corporation before Mandarin's plan to "improve" humanity kills billions. Can Tony stop Project Ultimo while being forced to work on it and can he and Zeke put aside their differences before killing each other?)
Captain America: No Escape. (Zemo may be a fugitive but he has one last trick up his sleeve. The Winter Soldier was once his father's personal assassin from back when and now Winter Soldier is put on trial in Russia for assassinating Nikita Khrushchev while working for Leviathan on orders from Heinrich Zemo during the 1960s.
Thunderbolts: Community Service (Iron Man appoints Luke Cage and Hawkeye to lead the Thunderbolts but not if Baron Zemo has anything to say about it. Will Zemo allow Loki's Wrecking Crew to go on a road trip of mayhem and destruction just to ally himself with HYDRA once again or will have prove that he's at his heart a hero?)
Ghost Rider: Avenging Angel (Zadkiel, the angel of freedom and mercy leads a second rebellion of angels against YHWH and takes the throne of heaven, casting out all angels loyal to the LORD. Ghost Rider isn't allowed back into heaven despite Lucifer and Samyaza being forgiven. Now with a demon-infested heaven and an empty hell, Ghost Rider needs to put things back the way they were so he can work towards his redemption as the angel of vengeance.)
Hulk: Fall of the Pantheon (Pantheon rebels when Hulk finds out that several of his own men are guilty of war crimes, Betty sacrifices herself to stop Hulk's soldiers, Rick Jones becomes the A-Bomb and Hulk is now blamed for all of Pantheon's crimes.)
Thor: The God Butcher (Gorr is angry at Asgard's resurrection as he seeks to destroy all immortal beings. Thor may have to team up with Dormammu to stop him.)
West Coast Avengers: The Gatherers (When a mysterious man known as Proctor invades our world to flee from an interdemensional bounty hunter called Magdalene, the Avengers must decide who's the real threat and learn that Proctor is actually the potential future of one of their own members. When they don't know if they can trust Magdalene's word that Proctor is evil, can they even trust Black Knight anymore?)
Mighty Avengers: Taking AIM (Monica Rappacini's science experiment goes incredibly wrong when her test subject usurps control of AIM and begins producing Super Adaptoids which have the power to copy any super power they come in contact with.)
Phase 7
Hulk: Planet Hulk (Iron Man shoots Hulk into space after blaming him for Pantheon's misdeeds. Hulk becomes an enslaved Gladiator and works his way up to becoming emperor of the Sakaarans)
Iron Man: The Inevitable (Arthur Parks is a brilliant scientist working for Tony Stark who finds himself building a harness that allows him to transform himself into a pure energy state. The catch is that a test goes wrong and Tony inadvertently transformers Parks permanently. Whereas Tony sees a man he needs to keep imprisoned to help him, Spymaster sees a weapon he can sell to the highest bidder. Can tony save parks before Spymaster unleashes a terrifying living weapon upon the Earth?)
Mighty Avengers/Thunderbolts: The Nefaria Protocols (Zemo's vengeance on Captain America is complete... except for the Extremis-powered crime boss who's working with Iron Man's ex-stalker/his daughter to unleash a highly addictive and lethal narcotic onto the market. Captain America and Zemo must completely bury the hatchet and learn to becomes true allies or else Count Nefaria will conquer the world. The catch is that Zemo already deployed an assassin named Bravo to kill Steve. This is the part where Zemo must truly earn his redemption and swear off world domination or become the irredeemable villain he always borders on being.)
West Coast Avengers: World War Hulk (Hulk returns with the Sakaaran army to get revenge on Iron Man and conquer all of Earth. Tony plans on fighting off an alien invasion that he's in part responsible for by lying to his team that Hulk sent himself into space and is nothing more an an insane conqueror. Hulk also owes Iron man a rematch from Age of Ultron.)
And none of these phases are complete. This is just what I want to see.
