What a great edit this will surely turn out to be.... and of all six even.... wowowow!
The Neimodien voices sound nice, but not when I watch the Passion of the Christ again I'll keep picturing them. I don't know if there's such a thing as "audio-morphing", but if so couldn't you morph one or two foreign language tracks and use them?
You could 'morph' the audio from English, Spanish and German for example. This would not be recognized as any language that we would recognize, which is what we need. And plus, it's all coming from a "Star Wars source" too.
I love the Maul/Grevious idea. We've all speculated, but you guys are actually going to tackle it. I love the idea of even having him in a scene in AOTC. And Count Dooku talking to Qui-Gon? BRILLIANT!
Needless to say, I will check back frequently and keep my eyes out. This will be a great alternate saga.
