You gotta set it after DS9 and Voyager but in the Abrams Verse... in this future, there is an inter-galactic war between the Dominion and the Borg. Humans, Klingons, everyone, are staying off the radar or joining the dominion. Get a Mos Isley feel for the series. Have a "crazy" El-Aurian (Guinan) talk about a different time, where all of the people were happy and have a new rag-tag group trust her and have her help in fixing it. Small ship. Three or four people. Couple of different ships. Rebellion. Whoopi Goldberg. And a restoration of the prime timeline. Hope amid constant fear of assimilation or death by Jem'Hadar.
