Welcome to SHH,
Windrider!
That Horseman layout is certainly possible for Season 2. My major concern with it would be that while it would progress the story further, it would make Cyclops look like more of a cad than he is already. He spent the entire first season being a selfish mope because Jean was gone, to the point where he abandoned the cause, his friends (even in mid-battle), and practically used Emma Frost until the moment she died to get Jean back. Suddenly having him ditch Jean in Season 2 to revive Emma would really make him seem less sympathetic than he already is.
The problem is that the finale of Season 1 may have left the writers with no better option. Had they sacrificed Jean to snuff the Phoenix, they would have expected viewers to feel sadness for a McGuffen of a heroine at best, but they would have allowed Season 2 to allow Scott and Frost to develop, as the comics are doing now (and have done for years). Instead, they sacrificed Frost, which gave us a more "tragic" death, but left no good option for trying to rekindle anything in Season 2. Now, I can empathize to a degree; the writers had no clue or presumption that WOLVERINE AND THE X-MEN would be renewed for 26 additional episodes, so naturally they had to throw their "best" stuff into the debut season, to make it high quality and to sell it. I get that. The only problem is now if they want to revisit Frost, they are left with poor options. Scott/Jean may be "kismet" to some long-term fans, but it hasn't been where Marvel has gone for some five years, and it's been done twice already in animation, and I was hardly looking forward to a third go.
Probably the easiest way to resolve it without making Cyclops look like a cad would be to have Jean start to fall towards Logan genuinely; maybe she finally realizes how much of an "emo stalker" Scott is for her and goes with Logan. That would leave Scott a much more desperate and sympathetic figure and justify anything done with or for Frost. There is one major problem with that, though; it would require the writers of WOLVERINE AND THE X-MEN to risk, if only for a moment, Logan not being ultimately correct or perfect in every single X-Men situation. A Logan who could, GASP, do something wrong or imperfect for a reason other than being mind-controlled or blackmailed by a villain. Nothing I have seen in the first 26 episodes leads me to believe they are willing to do that. Wolverine is Captain X-Man Esquire at the end, basically. I can imagine Jean making an overture, Logan being "honorable" and declining, but Scott being overly melodramatic and rushing off to Apocalypse or wherever Frost has been revived. Scott's usually been the type who overreacts at best in this show. The definition of "emo", yet he cannot even do "emo" properly to elicit sympathy. At every opportunity to make Cyclops look weaker and inferior to Wolverine morally, physically, and spiritually in this show, the show has taken it. I doubt that is changing simply because X-MEN ORIGINS: WOLVERINE fell 70% in week two and now is unlikely to match even X-MEN 2's grosses.
Part of me wonders if Wolverine, after a dominance of 20 years, is at the cusp of mass media overexposure. Many people who wanted to see X-MEN ORIGINS: WOLVERINE was psyched not only because of Logan, but because of Gambit and/or Deadpool. FOX knows well they can't sell a Wolverine movie on Wolverine alone, hence why the perennial guest stars. And, perhaps, why we didn't get a solo ADVENTURES OF WOLVERINE TV series. It's a dilemma; they know he is very popular, but needs the X-Men to complete the sell. I am curious how Season 2 will reflect this, or not. Season 1 reflected it by, while having some 7-8 Wolverine solo or "team up" episodes, devoting 3 episodes each to Cyclops and Nightcrawler, and usually doing better with nearly any episode that didn't exclusively star Wolverine in terms of quality.
In the comics, Jean managed to resurrect Emma Frost, albeit with Phoenix level powers. It is possible that the X-Men in Season 2 could find a way to resurrect Frost and then we have a bit of a triangle with her, Jean, and Scott again, only all three are in the mansion interacting. But that seems far too mundane for the X-Men. Everything with them has to be overly serious, grim, and dramatic. They can't just get junk-mail; it has to be junk-mail from MISTER SINISTER and SUGAR MAN or something. So my money is on Apocalypse, too.
There is a part of me that thinks it would be interesting if Season 2 starts with Wolverine as the natural BMOC and Cyclops feeling a bit resentful of it, given that Xavier used to be HIS foster father, and while he has Jean back, Jean's always been curious about Logan, and, well, Logan filled the position Cyclops was unable to (episode 20). It could be interesting; Cyclops as a bitter Never-Was even with his girlfriend back. The only problem is that would imply some sort of redemption path, but only Wolverine is allowed to redeem himself on this show (or Frost, I guess). Season 1 seemed to imply some sort of redemption path for Cyke, but it went nowhere. He ended the season no better than where he began as a character; hopelessly obsessed with Jean to fulfill his own low esteem, and in no position to hold a candle to Logan's leadership gusto.
I do wonder how Cyclops would fare in Season 2 as a villain, since the show's writers struggled to make him a hero, since he couldn't really rival Wolverine, who was the star hero on a path to redemption that he resolved. It might be interesting if Apocalypse and Mr. Sinister played it not just as being nasty villains, but as accepting someone that Xavier and the X-Men have clearly ignored and cast aside. Hey, they even brought back the only woman who loved Scott and didn't see him as a retainer to Logan.
"Sure, we're the so-called 'bad guys', but what have the 'good guys' ever done for you, Cyclops? You were on the verge of destroying yourself in grief for your lost Jean, and the only person who cared was the Hellfire Club's mole and the cause of said grief. Your so-called foster father abandoned you the first chance he got for Wolverine, the better, cooler kid on the block. The other X-Men rally around him as they never have, and never will, for you. With the X-Men, all you'll ever be is a footnote on Wolverine's trophy case; at least with us, you can be our star general, alongside a new love and your best friend. Join uuusssss...." Executed well it could be interesting; part of me fears that whatever happens will make Scott look like more of an unsympathetic cad than Season 1 did, but the other part figures that there's really no undoing that, so may as well go along the natural conclusion and see if the writers can get a better handle that way. You know there's no way they'd dare do a real Wolverine vs. Cyclops fight unless Cyclops was clearly "evil" or working for the bad guy. Only Wolverine is strong enough to break free from bad guy manipulations, after all.
Colossus had a redesign in AGE OF APOCALYPSE, and while I would like the show's writers to focus on fleshing out the characters they have, I'd clearly trade Forge for Colossus. At least, if the storyboard team has finally figured out how to dramatically depict a strong man in a fight sequence.

I could forgive Colossus looking like a sad sack, though, if they got his character right; he was usually the uptight "good guy" on a team of cynical veterans or anti-heroes, and that worked for a while.
I am curious to see how Kurt and Wanda's relationship will develop. It was one of season one's few genuinely good surprises.
