Githzerai would be cool, Aasimar would be interesting but I'm not sure how well they would translate to the CRPG aesthetic. I wouldn't mind seeing goblins and hobgoblins because they are already integrated into the game. It's like I really think warforged are a brilliant idea, but I don't think they really work in the Forgotten Realms.
Classes I'm less sure of, but would probably prefer more subclasses of existing classes rather than whole new classes.
