I could easily have someone transcribe the phonetic words of the reversed spanish and when spoken back it would sound like a new language.
The problem is making it sound professional and not like some guys sat at their computer and recorded themselves.
Though I actually spend a lot less time on these than people think. It's not like I spend hours on end slaving away at these things. It's like 10 minutes here, an hour there, in my free time when I'm not working on something else or an idea pops into my head.
That's why the original Balance of the Force took over 2 years to finish. It actually took another year or so before it got leaked around enough that it was bootlegged at comic shows and ebay, at which point I let Rikter distribute it online.
Oh, btw Biz', you'll be pleased to know that you'll be able to watch CW with Dooku as a Sith if you're so inclined on the new disc. It's not that way in the movie proper, but its a selectable option in the special features.
