I wish there were a way to insert Alderan. It is the ONLY time in the entire series (not to mention, the last time) that we can see it. I want to find a way. I had thought about maybe having the meeting between Yoda and such take place after the Tantive IV arrives at Alderan, and then cut to Padme's funeral (perhaps extended a bit with some other footage or even with the matte painting as well).
I'm gonna play with this further. Plus, I wasn't sure if anyone had tried this, but there is some unused footage in the trailers which i'm going to incorporate. It's only one shot but there is another that might be usefull for the mustafar battle sequence (it's Anakin walkign down the hall)... and there is another of him looking all emo but it hadn't been digitized yet so... just fyi.
As for the yoda thing, I personally want to keep at least some of the vision the same. I want it to be like Yoda has failed and is on Polis Massa and is watching Obi-Wan to make sure he succeeds... and then Qui-Gon enters into the vision and brings it to the future... padme's death and anakin's crawling... I might toy witht hat again.
