There would need to be an explanation for why the time traveller stopped off in the present day to recruit more X-Men to go the 60s. Presumably, because the future X-Men were all dead and the traveller wanted to assemble a team/back-up for the mission.
Yea I'd say the time traveler would be someone who was surviving in the future world with Wolverine, Storm, and Magneto. Those characters die trying to get the time traveler to the past or are just too old to make the journey at that point.
