Mmm, I am a fan of the GTO Manga. I would be most interested in doing Urumi Kanzaki, if you are having a hard time finding someone to fill her role.
I think I could easily pull off the Manga-version; what does she look like in the Live-Action GTO?
Regardless, I don't even know if I'll be going to the same Conventions you are. I'll be probably be going to Anime Central, Otakon, and Anime Boston for sure; the rest all depend on how much money I have in the bank at that time!
