Lots of good ideas, RL! It’s becoming clear that Boba Fett is the key to all this…if we can get him working.
The nice thing about the Vader to Boba segue is that any scene set on Tatooine would work there, such as the dance number. You could just have the shot from the Special Edition of Boba entering the party sometime during the song to imply that he just got off the phone with his boss. Heck, just replace the existing shot of him in Lapti Nek and call it a day 😉
