We complain about such changes as Han shooting first, and you propose a reboot? Like that new Star Trek movie? That has very little in common with the original? Part of our love has to do with nostalgia and the actors - your idea deprives us from that. Star Wars isn't just some n-th version of the Three Musketeers, that's shot every other year...
If such thing was possible at all, I'd like a reboot of the prequels (because they'd better not be made in their present form, I disavow them). Who will guarantee that those new ones wouldn't be even worse abomination?
One of our early forum members was once re-writing the PT from scratch. I too had a lot of own ideas. If it wasn't for the license, I'd at least team up with a comic artist, to show you my take on the story and visual style.
