"I always thought you could turn the six episode saga into three episodes, by taking each episode of the OT, intercut flashbacks from the Prequels (Godfather II style), telling Luke's story and Anakin's story simultaneously, and depending on what you reveal and when you reveal it, you never have to lose any of the surprises (Vader as father, Leia as sister, etc.). This is great because you only keep the good parts of the Prequels and don't have to deal with Jar-Jar or anything else you don't want to."

That's an outstanding idea! Then you could focus on the "meat" of the PT, and get rid of the fluff.
