I do have a question, would it be possible to add scenes from other films to make it make more sense add a new spin?

In terms of main characters that's obviously an issue, but could we add Grevious in? And fit in more battle scenes? Could we for example add in some of the Coruscant outside battle scenes from RotS into AotC, could some of the extra scenes like the politicians chatting be added from RotS to AotC.

One of the edits starts with Dooku and Palpatine having that chat they have at the end "the war has begun" etc - Which I actually think is the best way to begin the film.
