Yes, that'd be great!
I may also be doing Hare Hare Yukai (and maybe the other Haruhi Suzumiya related dances) with a Mikuru and Yuki if I can convince my friends.
One is coming to the con for sure and I have a costume in her size. The other it will jsut be expensive getting the costume and she'll have to work hard to get permission >< She'd be the perfect Mikuru though. (Baby face, big boobs, super cute. Tall, though, ahaha.)
I have a back-up Mikuru in case, though. I really want this to happen xD
