Terible, terrible list.
Maddrox and maybe Pym (only if he is allowed to abuse his wife on screen, because that would be awesome.)
Deadpool doesn't work because no actor would want to spend the entire movie with a mask on. damn it they kept finding stupid ways for spider-man to throw off his mask in the most public places. "Oh **** a spark, I know ill take my mask off for the entire train full of people to see me."
Cable is a boring hero with a bunch of abilities which are all boring. Plus his entire story would have to be re-written, seeing as how he is the son of X-men's Cyclopes who was sent into the future because Apocalypse had infected him with a techno-organic virus since Mr.Sinister engineered Cable by getting a clone of Jean Grey to have a child with cyclopes and.... see, no way in hell is there a Cable movie.
Nick Fury would be better in interconnected movies (like is already planned.)
