There’s no reason to believe every anthology film will be a solo character spin-off. We’ve only had one anthology film so far and it wasn’t that.
Yes.
My dream spin-off would take place in the SW galaxy, but feature no characters we already know and have nothing to do with the Rebels vs. Empire/Jedi vs Badguys ect.
Clerks set on Dantooine.
Dantooine is too remote to make an effective Spinoff Trilogy.
