Yeah, I’m not crazy about that deleted scene, especially given the shape it’s in. Best of luck to anyone who wants to try to incorporate it, but I’m not your guy for it.

We can mash up every possible combination of Jake Lloyd, Hayden Christensen, and Sebastian Shaw in each of their respective appearances. Make ROTJ Jabba look like 1997 ANH:SE Jabba. Have James Earl Jones’ Vader mutter “wizard” to himself as Luke evades his TIE in the Death Star trench. Map Tarkin’s face onto itself for ANH to match the uncanny CGI Rogue One version.
Hmm… I should throw in one more. Let’s say… recast Obi-Wan’s ghost to be Ewan McGregor throughout ESB and ROTJ.

All these things would be tons of fun, but I don’t really see any practical use for this technology for Star Wars at this point in time, at least visually. None that I would actually want to be included in a real project, though I would love to see any of the above as mockups. There’s more potential in the audio department; that could yield some very useful results for edits.
