Haha - yea, I sorta realized after the fact that maybe I went into way more detail than you were really asking for
Sounds like you got quite a bit of custom parts yourself! Nice to hear about Emilio's whips as well. They look really good and it's my understanding they aren't too expensive either.
Speaking of the bag- I did forget to mention that I also replaced the strap and buckle with something more accurate and also have one of TonTon's glowing bags which is so cool!
I would maybe practice on a cheap throw away head when it comes to the dremel just so you can get a feel for how much speed you need and how much force you need to apply before hacking away at the original TOD sculpt. If you don't have a random spare sculpt to work on, you could always buy one of the cheaper recasts of the Sideshow TOD sculpt from eBay that way you'll pretty much have a copy to mess with but still see how it would work out and look.
