Alright, the sign-up is up. I'm impressed with how balanced everything seems to be with the variant (though time will tell, I suppose). I do agree though that you should separate out your other homebrew rules. Racial feats are part of the Generic Class system but some of the other stuff really isn't.
Please chime in and monitor the character creation process, I'm sure you can answer some of the questions more quickly than I and would probably benefit from seeing people create characters for the variant first hand.
