All of them except for the time traveler or Prof X( Depending on how they go about time travel). I left Kitty just cause she was used in the book and we have no facts on who the other time traveler could be yet. No one else is crucial to the (future) story as of now , so besides the traveler and whoever sends them there everyone else can be dead imo.

Id be cool with that but I have no interest in seeing a tombstone cameo for Psylocke, They have already killed that character literally and in terms of adaptation, no need to twist the knife if she was never shown as an X men.
