I would go to see another film with Rey becoming a Jedi Master and taking Finn as her apprentice.
We could finally see the Republic restored and the Jedi order rebuilt.
I don’t know if you could do an entire trilogy out of it but a stand alone episode 10 maybe.
I don’t see Lucasfilm doing that though.
Also conflict makes good drama, well the conflict of Star Wars is played out you can only do so much Jedi VS Sith stories, or rebels vs empire.
