Ah, very cool. This really gets me thinking...if Maul remains the primary villain in a trilogy as I've suggested, it means that Dooku can be scaled back a great deal, but still left in. I know many have toyed with the rogue Jedi, thought, and perhaps that could still be implemented. He could remain an unwitting puppet to Darth Sidious, but not a willing apprentice. In Ep III, all references to Palpatine aboard Grievous's ship would be removed, and Grievous would merely be Dooku's General. Dooku really would be a Force user who simply wanted to expand his powers, but not an all-out Sith. He ultimately takes his Separatists and parts from the Republic, and while his methods may be grim, he is not purely evil, but rather a misguided Force user. I dunno, just tossing ideas out there. Nothing could possibly happen till the series is over anyway.

EDIT: Here's the pictue I was referring to. Not sure if it's a real screenshot or someone's attempt to replicate it, but here it is anyway.
