Sorry if this has been covered already, but I don't have time to go back and read all the posts right now. I think that Adywan has an opportunity here to, instead of omit 3PO, do him justice. He could do so by using audio samples from the many EU projects that Anthony Daniels has lent his voice to over the years. This would be similar to how he added Luke's "Biggs!' dialogue in ANH:R using an audio sample from the radio drama.

The same could be done for General Grievous using audio samples from the new The Clone Wars animated series since Matthew Wood does the voice. One scene that comes to mind, where this could be useful, is the final confrontation between Kenobi and Grievous where Grievous bites the dust without uttering one line of dialogue.

Also, in regards to annoying battle droids, you guys should watch Episode 5 of The Clone Wars. It's titled Rookies, and shows off some new battle droids that are a bit more menacing than the Trade Federation droids. I don't know exactly how Adywan might utilize this, I just hope that it sparks some inspirational thought.
