Tales of the Jedi from the comics, the Great Hyperspace War. Freedom Nadd, Ulic Quel Droma, Exar Kun, etc. Big, galaxy sweeping stories with big consequences set so far in the past that they don’t impact existing IPs.
The alternative is a dark anti-hero movie with Young Vader taking on a huge terrorist crime syndicate with the plucky crew of a smuggler’s ship caught in the middle. One of the crew has a mysterious past and a dark secret, while the Capitan has a personal grudge against Vader.
