I once again dredge out my decade-old concept of the rotating anthology series.
Four different series, by four different production crews. Each series features a different Trek crew and time period. The shows all appear in the same weekly time slot, each one appearing once a month. Given a 24-episode season, each show would have six episodes.
Week 1: The Romulan Wars, featuring the crew of a Starfleet warship.
Week 2: Kirk-period stories featuring a different crew and ship.
Week 3: Enterprise-B stories.
Week 4: "current" Trek period stories, featuring the crew of the first starbase in the Gamma Quadrant.
Yeah, I know, impractical and expensive. So what, we're dreamin' here.
