Rebels cartoon costumes?

My son and daughter love watching the new Star Wars Rebels cartoon. We are heading to Celebration in April and they had a great idea of our whole family dressing as the Rebels gang (Ezra, Sabine, Kanan, Chopper). Does anyone know of a source for quality costumes from the series? And I don't count the cheap Halloween costumes. Thanks!

My two suggestions would be to join the Rebel Legion boards or the RPF to see what those folks have cooking in support of this series. KW Designs/Imperial Surplus has made new AT-RT armour and helmet sets already. I wouldn't be surprised if he's crafting hard/vac formed parts for the other characters. As for the young lady Mando in the series (I haven't watched it), look around here for Shae Vizla/Death Watch Mando kits. They come in male and female forms. In fact, I think Kevin does those too.

Kw also has some hard parts for Kanan
