I do think that the dystopian future will be an alternate timeline rather than a "sequel" to X3 or X2, especially since Singer actually mentioned an alternate timeline in an interview. So yeah, Cyclops and Jean could be in it.
As far as continuity issues go, if you take a view that this dystopian future is an aberration that should never have existed and should never have been a part of continuity in the first place, then it would in essence only exist for the sake of this one film. IMO you run into way, way many more problems and confusion if you try to somehow fit in the dystopian future into the same timeline with X1-X3.
