A really ambitious project would incorporate Grievous in all 3 somehow, like the guy who made him Maul.

Maybe…there is a way to incorporate grievous even earlier. Maybe into the ATOC droid army. Or even further into the Neomoidian army as a lowly TK4 Roger Roger droid who wants to be more.

Or even more ambitious…make him Darth Jar Jar after all.

If I had the deepfake skills, I would edit in Maul and Grievous and Dooku to meet.

In fact, that sounds like a great idea to set up a different timeline. Instead of going Sith, Anakin is defeated. Killed? Lost? Captured? We don’t know, and the Sith make their revenge easier with 4 Sith Lords instead of 2.
