Does anyone else think that AvX would be a good way to divorce the X-Men universe from the rest of Marvel?
All too often it seems like the persecution of mutants only happens within the pages of the X-books and the rest of Marvel's books may touch on it occasionally but it never seems quite as bad as it does in the mutant exclusive titles. At the end of AvX, they could release two finale issues...
In one where the Avengers win and mainstream Marvel (the 616) continues on without the X-Men... maybe some individuals survive here and there, and mutants as a whole aren't wiped out, but the "mutant crisis" or mutant threat is just back-burnered. This would allow them to keep Wolverine in both worlds, as well as maintain a rather significant number of non- X-Men specific mutant heroes and villains. Mutants are just no longer the big background threat society alleges them to be and what remains of them could move forward with integrating into regular society as many other mutants have successfully done.
In the other, the Phoenix Force decimates the bulk of the Avengers (and maybe sends the rest packing with scars they'll never recover from)... but the mutant population surges again. And with it, more race persecution and a rising concern that mutants are a dangerous threat to the world (since they could be blamed for killing the Avengers). Then their story can continue merrily on its way toward whatever bleak, dystopian future the writers wish to portray without the more accepted superhumans lording it over them like "We've assimilated, why can't you?"
Everybody wins! And maybe we could kill off Wolverine in both worlds instead of having him live on in each.
