That wouldn’t be bad either! But yeah, it would be hard to do both with the structure as-is. That is partially why I had the idea of just replacing it.

The thing is, you could cut out the Separatist leaders leaving Utupau, we can see Grievous talking to them, then Kenobi jumps down. Presumably the Republic fleet is already there since the clones repel down just a few moments later, so it would’ve been unlikely for them to escape anyway. Their story could end there.

And I think it would fit better if Mustafar was Anakin’s first “hunt” (not counting the massacre of the Jedi temple), because that sequence is intercut between Obi-Wan and Yoda witnessing the aftermath of the temple slaughter, Obi-Wan asking “who could’ve done this?” and hard cutting to Anakin killing more Jedi. It also intercuts with Palpatine elaborating on the Jedi’s “betrayal” and how the remaining Jedi will be hunted down and defeated. So we would literally be showing Anakin doing just that as Sidious talks about it.

Also, I personally think it would be more visually interesting. Slaughtering the Separatist leaders isn’t a challenge at all for Anakin, but taking on a group of Jedi, like 5 to 1, would probably be more entertaining to watch.

To do it, this would be what you would need:

Some kind of CG model of the control room to use for the background.
Maybe about 5-6 actors to play Jedi and a hooded Anakin. Either local actors and buy costumes, or maybe contact cosplayers and cover their travel to film the shots.
About 10~ shots of: Anakin entering the room, the Jedi grouped together acknowledging Anakin, and various quick fighting/killing shots.

My local university has a nice green screen in their studio, which we could use as an option to film these shots. It would take some effort but I think it is comparable to some things Ady’s doing, so not impossible.
