Okay...so you're suggesting a time-jump to a period in the X1-X2 timeframe. So how does the 60s setting of First Class factor in? That would need another time-jump.
I have no problem with your suggestion. Or, for that matter, with seeing the return of Xavier, Jean and Cyclops, and a repowered Rogue and Magneto, as long as there is a logical explanation (hopefully one that's clearly stated or is very obvious!)
