This is a fantastic idea. I found the novels far superior to the films. If you guys successfully pulled this off, I would be first in line to take a listen!

As an alternative idea, since no one here has the resources to completely remake the prequels in film format, it might be interesting to remake them in audio drama format. I think it could be really cool to create the prequels in a manner closer to how GL originally described them, and preferably with a likable Anakin, Kenobi as a real General, the clones as bad guys, no droid armies, etc. I know folks have attempted some ideas in the scriptwriting section. This might be a good venue to make better stories become a reality without the budgetary and legal problems of remaking the films.
