That, or a series depicting the run-up to the Feddie-Klink war in Star Trek Online. It's sufficiently far in the future for things to be somewhat different, but close enough that the stuff we remember still has an effect (stuff like Romulus blowing up, and the Dominion War) - and you could get a guest star character or two in there.
