It depends on who they use as the time-traveler. If they go with Kitty, I don't even care who she runs into in the past because she didn't make any strong connections (on-screen) with any of the characters that would exist in X3. Obviously, I'm not rooting for her to be the time-traveler unless it's as part of a group.
For anyone else (like Logan, Storm, or Xavier's consciousness), it would be just OK if it was Xavier, Mags, Mystique, and Beast. But it would be AMAZING if they were to encounter Jean and Scott due to the fact that they're dead in the future and they had to grieve them. (You can argue that Storm may have met Havok and Banshee sometime between FC and X1, but that would be a hallow farce.)
