Ronster and Darth-Ender: I think both of you are right: you need a guide, a list of what you want to do or not. So the vote seems like a good start. But you know some of this changes will face the truth of what can be done or not in the end (and how many time people want to spend working on them. Because some things are doable, but would require more time).

The only thing you have to keep in mind is: if some ideas finaly can't be done, does this affect the other ideas or not? If most ideas can be abandoned without creating plot holes or that sort of things, then it's okay. People can give it a try. If it's a succes, it's great. If not, so be it.

What you don't want to happen is having a problem in the making of a new scene that you MUST do for your edit to have a sens. A list of those type of scenes could be done to check them prior to the others. To see how they can be done.
