You mentioned the possibility of redubbing Mas Amadda's lines to get a better voice. He's the blue guy who says "O-dah!" etc. I'd be interested in doing that, to see if you liked how I did it. (If not, that's fine, lol.) I have done some acting and work with accents in the past, though not all that much.
Actually, I'm nervous of volunteering, but hey, it's worth a try at it.
