Seems like a pretty moot point, since this show is effectively dead. The excuse that Lucas is "waiting for technology to catch up" is pretty pathetic. People are making good sf/f now, and making money off it. If Lucas needs technology to tell a good story, then I don't trust that he has a good story to tell. A pencil is all the technology you need to tell a good story.
And all this effort is unnecessary. I actually think Lucas already has the right solution to getting Star Wars on TV - The Clone Wars is not only a way to do eye-popping stuff on a cable TV budget, but it also has talented writers and voice actors that make it far superior to those dreadful prequels.
The essential problem is how to make Star Wars more intelligent and sophisticated so that it has enough "meat" to provide years' worth of stories on TV, yet still feel like Star Wars. The OT is great, but that approach only works in movies. On TV it would come off as pretty thin on both psychology and politics. Just extrapolating that approach to TV isn't the answer.
The prequels managed to lose all the fun and joy of the OT, while being heavy handed and unconvincing in its depiction of psychology and politics. And there was nothing on the metaphysical/mystical front at all, which should be the heart and soul of Star Wars, since it's the feature that most distinguishes it from most space opera sci fi (and the feature that results in criticism that Star Wars "isn't sci fi," but who cares about that.)
The Clone Wars' solution is to start with the fun/joy/kid-stuff wild romp that Star Wars should always be, and then incrementally add in psychological, political and mystical storylines. Under Dave Filoni's direction, they have found just the right compromise that manages to appeal to grownups and kids alike, and it is right on the money for feeling like Star Wars.
Compared with that, bringing in a whole new crew that hasn't worked on Star Wars before (to my knowledge), and trying for something like The Godfather (!!!???) is just asking for trouble. Writing stories that do feel like Star Wars and not a hundred other things is probably a lot harder than it looks like from the outside. Odds are that they would completely miss the mark.
Lucas has a good thing going. He should continue Star Wars stories with Dave Filoni and the current crew of animators, writers and voice actors. When The Clone Wars' story is over, launch a new animated series right away, bridging the gap until ANH. (I wouldn't mind one little bit it Ahsoka managed to survive the purge and continued as the lead character.)
And if Lucas ever wants to add a live-action series to his existing animated show roster, he already has a successful writing crew. He should just turn the live-action and animated divisions over to Filoni's direction and let him expand the ranks as needed. I see no reason why writing for animation is fundamentally different than writing for live action.
If it ain't broke (finally!), don't break it. Again.
