I like the idea, but expand it a bit to be an arc of 2 or 3 episodes for a story, sort of like what Enterprise did in it's final season. That gives a lot more room to work with in terms of storytelling. A traditional TV series would require at least one re-occuring character, but since this is Star Wars most viewers would be able to accept your concept Tydirium, especially if there was an overall link to each arc.
How's this for an idea for a recurring character?
The recurring character could be Yoda, sitting on Dagobah, and using the force to follow galactic events. Sort of like Alfred Hitchcock in the series he had years ago. He somehow introduces the characters and the situation they're in, and we watch it unfold. Then he shows up at the end and gives some sort of moral to the story.
