Fox should hire you.
Or someone like you.
Thank you. They already have Singer, Millar, Kinberg and Donner for that. I just come to these forums to pass along fan ideas. (And keep in mind that Fox filmed Kinberg's rough draft for Fantastic Four, Millar got kicked to the curb by Josh Trank and Singer and Donner wanted no part in that abortion.
If you want to hear a really mindblowing idea, it's that I'd sell back the Fantastic Four film rights altogether and have Phase 4 introduce the FF in their own film while making Doctor Doom the main antagonist in Black Panther 2 and then use Kang as the big bad for Avengers 4 in exchange for allowing continuities to merge at the end of Phase 4.
If Legion is a success, I'd run it through 2023 and much like the Age of Apocalypse story, I'd have him be the man responsible for destroying all realities. What happens is that Kang returns to the past to conquer Earth during Avengers 4 and succeeds in doing so and his game plan if he loses is literally to DESTROY REALITY.
Meanwhile, in the Fox-Men universe, I'd set things up so that after the defeats of Stryfe, Sinister and then an X-Force film that would follow the plot structure of X-tinction Agenda with the central conflict based on Second Coming and with bits of Welcome to Genosha and Zero Tolerance thrown in to act as a culmination of the current X-Men world where Cameron Hodge and Bastion are defeated and Magneto is the current ruler of Genosha, I'd use that a good jumping off point for the franchise. This loops back to the Legion series where Legion winds up seeing these other realities and finds that his powers have developed to the point where he can manipulate them and decides to completely wipe that post-DOFP timeline as well as the MCU from existence and create a world where mutants like him are in charge... which leads to the 2023 Age of Apocalypse film. What happens is that he also sees a world where his friend Quicksilver is dead and that in a way, breaks him and he wipes the MCU away right as Kang destroys reality itself. Needless to say, this will also be a series finale for Legion. keep in mind that with Apocalypse's defeat in AOA, reality still does not return to normal thanks to Kang.
So after Kang Dyanasty and Age of Apocalypse are over, what happens is Legion's meddling in both timelines has caused them to converge and for Doom to rule what's left of various timelines with the MCU and Fox-Men being the centerpiece in a two part event where one film is produced by Disney and the other by Fox. Secret Wars would also get cameos by Wesley Snipes, Thomas Jane and Tobey Macquire.
And the aftermath is a universe where both studios retain their casts but crossovers are now allowed. We'll see Captain Marvel and Deathlok join the X-Men, Wolverine, Rogue and Beast join the Avengers and Agents of SHIELD will get new members in Abigail Brand, Garrison Kane and GW Bridge. We'll also get a Guardians/Inhumans crossover based on War of Kings. A young Hank Pym and Doctor Faustus, Red Skull, Sebastian Shaw and Madame Masque are now in the present as is the X-Men roster from what would be around the 1990s in Fox's continuity and Ronan is alive again.
Not that this will be all sunshine and rainbows. Phase 5 should be an adaptation of Dark Reign since reality merging actually made some things WORSE. Norman Osborn is now director of SHIELD and Red Skull now sits on the World Security Council. The international community has responded by creating their own national teams with two of them going right to Fox's TV shows, Hellfire and Legion will be replaced with X-Factor and Alpha Flight. (Psylocke is American in Fox's continuity so it's doubtful that we'll ever get a Captain Britain film from Fox.)
Oh, and the sentinel program is back. Bastion survived the last pre-Secret Wars X-Force film and he's now part of SHIELD.
IMO, part of the reason why I really want Abe Jenkins to be the villain in Ant-Man and The Wasp, I want the villain of a second season of Luke Cage to be Atlas, hope for an Iron Man 4 based on Armor Wars with Ghost and also want to see Scorpion, Joystick and Shocker in the Spider-Man reboot is because I REALLY want to see the rumored Thunderbolts Netflix series to happen. By the time that Phase 5 hits, we'll not only see Zemo and HYDRA be effectively less evil than SHIELD but Moonstone will switch sides and betray the T-Bolts and then be the villain for Captain Marvel 3 and possibly kill off a member of the T-Bolts like Jolt, Blizzard, Ghost or Shocker (since let's face it, only Helmut, Abe and Mel really have plot armor) and Hawkeye sees how SHIELD is compromised yet again and joins the team in Karla's absence with him first showing up at the end of an episode uttering the words, "Hail immortal HYDRA." And not only does Norman Osborn's SHIELD destroy Magneto's Genosha with Sentinels killing millions but Norman also personally kills Gwen Stacy. X-Force are now treated as terrorists, Tony Stark is a fugitive, the X-Men and Avengers have their hands tied by bureaucracy, the Fantastic Four are kidnapped by Doctor Doom in Latveria, SHIELD have bullied both Thaddeus Ross and X-Factor into invading Wakanda, Daredevil's identity is leaked to the press, Wolverine is framed by The Hand and only Elektra can save his good name, Shadow King has brainwashed the X-Men through Cerebro and only Storm escaped, Alpha Flight are openly clashing with SHIELD, Asgard has appeared above Earth setting the stage for Avengers 5 (which is Siege) and Steve Rogers is investigating a terrible disease that Germany's representative on the World Security Council may be responsible for. The MCU may have gotten more expansive but it also became a much worse place by most people's standards.
Agents of SHIELD will have some really great network crossovers with X-Factor and Alpha Flight on TV but Thunderbolts would mostly do it's own thing with SHIELD characters showing up in a few episodes.
Phase 5 is where the MCU should get just as dark as the X-Men films do and the only exceptions to this would be Guardians of the Galaxy, Spider-Man and Deadpool since I never want to see those properties go dark and gritty.
And Phase 4 needs to be where the MCU goes lighter than stories like Civil War, Infinity Gauntlet and Ragnarok. It should be a breather from 2020-2023 focused more on expanding properties in new areas and growing supporting casts instead of tying everything together for a big event like Phase 3 is doing, then have everything come crashing down with Kang.
And as for what Marvel should be working on from their end, I'd suggest that they add some Q4 dates to 2018 and 2019 to do a Black Widow film dealing with her past and have Yelena Belova as the villain on the former date and then end Phase 3 with Iron Man: Armor Wars that'll be Robert Downey Jr's swan song in the role and introduce Ghost, Spymaster and a new Iron Monger to the MCU.
Phase 4 should up the production schedule to four films a year with films that are either low budget or high risk getting the Q1 dates to save the sure bets for the summer and the years opened by new IP or in Hulk's case, failed IP.

2024
Secret Wars Part 1 in May. Part 2 in August. One directed by the Russos, the other by Bryan Singer. Filmed as a co-production with one studio getting domestic and the other getting international with Fox getting physical video and network TV rights and Marvel getting digital, premium cable and streaming rights.
And X-Men and X-Force should alternate each year just as Wolverine and Deadpool should also alternate. Every year that we get X-Force, we also get Wolverine. Every year that we get X-Men, we also get Deadpool.
The eventual rosters should be by the time of Secret Wars which should be around the mid-late 90s by X-Men time.
X-Men: Wolverine, Cyclops, Storm, Nightcrawler, Phoenix, Bishop, Iceman, Xavier, Shadowcat, Rogue and Colossus. Magneto would have recently left the team to rule Genosha.
X-Force: Cable, Deadpool, Psylocke, Archangel, Domino, Siryn, X-23, Fantomex, Warpath, Sunspot, Hope Summers
Post-Secret Wars, I'd like to see X-Factor's roster be Havok, Mystique, Forge, Quicksilver, Strong Guy, Rictor, Shatterstar, Multiple Man, Layla Miller and eventually Wolfsbane as a liason from the UK. Deathlok joins X-Force and Captain Marvel joins the X-Men. The first Phase 5 X-Men film should be based on Mutant Genesis, Fatal Attractions, Magneto War and E is For Extinction with Magneto framed for some atrocity, some country retaliates by deploying a recon sub and Magneto crushes it and kills the entire crew inside. The X-Men (along with Captain Marvel) are sent in to defuse the situation and eventually SHIELD just blow up the entire island with Sentinels.
The second should be Brood Saga where Cyclops meets his father to help the Shi'Ar fight off the Brood and Captain Marvel becomes Binary.
