He'll probably be reverted to the Red Skull at the end of the crossover. In any case, Xavier wouldn't be so crass as to take the O5 away from Professor K.
Xavier is incompetent so no.
No Skullslaught would just manifest once more and be usedfor awfull storytelling.
Well, the Avengers already kind-of consider the X-men as threats to everyone, so being lead by Captain America's arch-enemy is next logical step in that regard.
no,Magneto should kill him. It will mess him up, killing what left of Xavier, and killing a Nazi leader. he would be happy but hollow win for him, a good read
The dream is dead, so wake up and fight!
I like the idea of him eventually leading the All New X-Men, it just makes sense. Or at least, guiding them back to the past with a message for his past self.

The O5 tried to go back to the past but they can't. Future Beast spent his life trying to figure why they couldn't so why Xavier would be able to? Anyway, it's not that sure that the O5 would accept to have the Red/White Skull as teacher or leader.
