The "I'm going to turn into a monster" bit, though very cute, doesn't really work, since Rogue was around 13 before she ever met Mystique, after her powers kicked in.

And do you mean she switched Kurt and Anna's powers in X-Men Forever? Because going out in public wasn't really an issue with Kurt, and hadn't been for years, since he either used the image inducer, or just was himself, so barring HIM the ability to ever touch anyone again might be seen as being just as cruel.
