She's not on Coscom, but a friend who does Rakshun (and debuted him at Fanime this year) just moved back east -- I think she's doing Otakon, but would have to check with her to be sure. Know she was talking some others into doing the series too, though I can't recall as what (or if they were going for this year). I'll let you know when I hear from her for sure?
Expect she'd be thrilled to see another JK cosplayer!
(As for me, alas, Otakon is too far and too expensive to be viable. Pity, I'd love to see your finished work!)
