My current idea is to use the same world, but the story won't focus specifically on the Jedi/Sith conflict, though it will likely still play out in a modified form. I'm definitely leaning toward an expansion of players, and an open world where players can create their own conflicts and even run their own mini "campaigns" through their characters. 

If I go open world, I'll allow  multiple characters, so that you don't have to figure out how to get your galactic Senator involved in the mystical battle on Dantooine. You just play whichever character is most fitting for the story you're taking part in. 

I'm sorry to hear that you're not into the "mundane" parts, but I know there's a lot of people with the opposite opinion too.
