1. Rachel Summers
There's no doubt that including Rachel Summers would be a pretty big deal for Days of Future Past, as she should be. It would help further make the Summers clan the forefront of the X-Men world, given that she is, in fact, the daughter of Cyclops and Jean Grey, though how this would abound itself is anyone's guess given the events of The Last Stand (unless they are mostly conveniently omitted or altered). Granted, the Days of Future Past story gets a little dicey with regard to Rachel's character - simply because there are so many different variations of her through the various timelines - but there are countless ways to tie all the ends together, and we're confident that Bryan Singer's firm directorial grasp of the material can do her justice.
