How about this fellow for Grievous? ;)
I thought the line @ 1:56 ("Hello Cutie Pie. One of us is in deep trouble") would be good for Greivous to say after Obi-Wan and Anakin are captured and brought to the bridge.
The "Chill out, dickwad" @ 2:08 would also be funny during Greivous' conversation with Palpatine's hologram.
But... if it's Vork you want, then it's Vork we'll get.
