Of course. I'm not suggesting that you're outright banning characters and if there's a problem with the issue of time-travel then we can work something out. Perhaps a one way trip style travel? Another mutant power? I'm open to suggestions on how to solve the issue rather than being simply told it's an issue. :)

"Using technology available to him in the future, Bishop constructs a time travel device. A device that, despite the technology of his future, can only provide a one-way trip to the past."

Solved. The bigger issue, and why we wince about time travel, is what happened to result in Bishop's future? Xavier's already dead. So it can't simply be that. Maybe...for some unknown reason, this team failed? Or, even better, maybe this team couldn't get to Fury in time to prevent HIS death? That'd work better for me, and will solve for me, the storyteller, how the team learns of Fury's detained location.
