There's no logical justification for bringing back Marsden & Janssen.
It would feel cheap & nonsensical, like Marvel bringing back Coulson for The SHIELD series.
Xavier & Rogue may not have been in the future faction of DOFP, but if Singer puts them in it could at least make sense. Same goes for Mystique.
Jean & Scott as children if Singer bumps up the FC faction to 1980 I could accept.
