I think more of the original X-Men movie characters will soon be signing in too. It's kind of required in order for their to be a future for the present day (meaning 60's version) mutants to contrast with.
And of course the details of the original story will have to be changed. It can't be Kitty Pryde who travels back into her younger self since she wasn't around in the 60's. The obvious choice has to be Mystique. With Jennifer Lawrence a much bigger star its natural to expand her part and have Rebecca Romijn again play her in the distorted future.








Sounds like a fine idea.
