Hi Joe, welcome to Clash!
The character stuff is unlikely to be coded for quite a while, so I can't really encourage you to propose model elaborations at this point. But there's nothing to stop you from finding the most recent Character model thread (probably down on page 5 at this point) and putting up a brief draft of your ideas. I won't be able to discuss it much though, since I am trying to focus my Clash time on the things that are being implemented now or soon.
If you want to push the game along, I encourage you to give your comments in the threads that are being actively discussed for implementation. That's where we need the most comments at this point.
Thanks for your votes on our poll too!
