I’ve actually been thinking about doing this with the new Dune films. I can imagine people asking what the point would be in doing it. I honestly just think it would be a lot of fun.
The second time I watched the new Dune film, I imagined that the events were taking place deep in the outer rim during the dark years after ROTS. When the Emperor was mentioned I imagined it to be Palpatine. The Lady Jessica’s last name would be Dameron, and Paul Atreides would someday go on to have a son named Poe who not only resembled his grandfather but would also long to be a pilot.
Duncan Idaho (who would need a new name) is an exiled Jedi in hiding who senses Paul’s Force abilities
The Bene Gesserit is an order similar to or perhaps connected to the Night Sisters
The Spice Trade from Arrakis would rival that of Kessel
Star Wars music would be used wherever possible, and the opening crawl would name Paul as Paul Dameron Atreides.
