Oh, I'd be interested in this too, so long as you don't have too many people already. I'm kind of tossing up between:

* Mai or Mikoto from Mai-Hime
* Someone from Mai-otome (A bit tougher to integrate into a shared setting)
* Someone from MGLN. Maybe Yuuno? I preffer to play characters from post-Strikers times, but they'd also be harder to integrate.
