Just another idea might be fun to toss out there...
A dark matter pulsar (why not?) and a black hole are in mutual orbit around one another. During an ion storm, a shuttlecraft is sent with some Starfleet crewmen to take readings. But the shuttlecraft that comes back has a different name. The uniforms of the crew aren't quite right, and they insist the ship is all wrong. What is this "Federation" anyway? What happened to the Grand Alliance?
We have three people evidently from an alternate history, and nobody can figure out how to send them back. But they tell about a danger the Federation doesn't yet suspect, but which the Grand Alliance only barely defeated recently. Starfleet asks them to accompany a starship to the region where this problem emerged, to see if it even exists here.
Yet the three Strangers have some secrets of their own. Not necessarily even shared with each other. Was this an accident? Or not? What if one of them meets someone who was their spouse in "their" world? Exactly what might this threat be, and did the Grand Alliance maybe cause it accidentally rather than fall victim to it?
Might be a multi-part miniseries in this idea maybe? Or a season-long arc for a new Star Trek series?
