For number 1 on your list, would the same person willing to rerotoscope Windu's saber be willing to do something similar to a lot of other people's lightsabers in Episode 2 and 3? A stupid little thing about the prequels is they kept putting things that were awesome and incidental in the OT into a formula in the PT.
"Darth" was cool and incidental in the OT because there was Darth Vader, but that was it, in the PT any John Q Badguy is named Darth Something-or-other: Darth Maul, Darth Sidious, Darth Douchebag, etc.
Okay off topic, that's just another example, the example I'm bringing up is lightsabers. In the OT, it's cool cause really there's only one bad guy lightsaber and it's Darth Vader's and it's incidentally red. And also incidentally we only see three other lightsabers the entire rest of the trilogy and they're Anakin's, Obiwan's, and Luke's--and they're blue, blue and green incidentally. In the PT it suddenly becomes a formula that good guys get a tough choice between blue or green and bad guys gotta have red. In the Star Wars expanded universe, like KOTOR for example, there's much more of a spectrum of color to the things. It'd be cool to see a sea of variety in some of those shots of everybody flexing their saber skills.
