It depends how they choose to do it. They might have the time traveller(s) say to pastXavier: "In our world, you rescued a boy called Scott Summers and recruited two girls named Jean Grey and Ororo Munroe. You need to find them - now- because you're going to need them if you still want to exist."
Doing this in a film set in 1973 could be tricky but we already saw a Storm cameo in Cerebro in First Class, so they might be basing it on that.
Whichever way you do it, the timeline is screwed up in some way and some things are never going to match up.
It would feel more logical for young Scott, Jean and Ororo to arrive in the next film set in the 80s, but I don't know if the studio will wait for another movie to bring them in.
If they don't bring in those three, we are likely to get characters like Polaris, Dazzler, Sunfire, Thunderbird, Quicksilver or Scarlet Witch.
