Y'know what kind of Star Wars spinoff I'd like to see?
A slick HEIST movie.
Like, an ecclectic group of crooks, each with their own specialty, have to swipe a metric asston of supplies and credits from say, an Imperial Overseer of some planet, or Bodega the Hutt.
Hell, make THAT part of the Young Han Solo serials.
Also, OP... So your idea of a rebooted Star Wars is a focus on the Wars, the pitched space battles, and a Good Guys vs Bad Guys on roughly equal footing, and maybe looking less at the Force.
... So, Star Trek? That sounds like Star Trek to me.
