I like your ideas.

Still a better viewing edit for the sake of enjoyance and stability and not only from fixing story is that you have to consider about changing the languages of the aliens so constant. Even worse if you have half of the movie with english subs. If you have the choice and the option to redub characters do it in english. Even more to british english like OT is.

Also if you wish to make your ideas in motion please clear if you want to make an edit with your style or the supposed style of george lucas if he was doing it right. that implies carefuly editing times, noticing the pacing adding fades and generaly add nothing more from the visual presentation that these movies offered. We rarely see subtitles, we see slowmotion only one time (thank zod) and the idea of overlaping images is a bit off for a SW universe movie. same goes to the flashbacks. You may want to analyse the episodes 4-6 to see how they did some things and how PT does it. Even the average time of shot per second counts to the feel of a movie.

Im not saying that you will do/intend to to these things in your edits but im like making a list of many things that the other editors did for the sake of story and they succeeded, but failed (IMO) to capture the feeling of star wars. Some things are not for this space opera please :P

Not want sound like promoting an edit but Trooperman's version/workprint with the redubing and the things that the characters are saying is the most solid part of this effort.

my 2 credits to the whole point of direction. Its pity so good ideas go to dust with poor decision of how they can be done fast and cheap.
