I like what you're doing with concealing Anakin=Vader. This looks like it could work (although it's not something I'd choose to do in an edit).
Concealing Leia=Luke's sister, though, doesn't look like it could work smoothly. The edits to the birth scene are to jarring, IMO.
The Yoda/Qui-Gon scene has the most potential though. Perfect line from Narnia; when I first saw it and heard that line I instantly thought "Episode III fan edit line!"
