I didn't really remove Dooku's Sith alter ego, just removed the name Darth Tyrannus because throwing a second name for him into the mix only obscured him even more. We didn't get much of him to begin with. Even if the scene with him and Sidious is removed from the end of Ep2, there's still enough in Ep3 to cement him into that role.
Anyway, I did not know that Clone Wars had a yellow lightsaber; that's pretty cool. It's not me doing the rotoscoping, so I'm merely utilizing what Jackpumpkinhead is doing anyway.
