EOY eh? You'll definitely need some stormtrooper company for that one. It'd be a bit odd walking around as a solo Imp officer; you'd need a bunch of grunts to order around to complete the image.
Yeah ideally I wish I could make it in time for STGCC but I think that's kinda pushing it. I'll shoot for EOY. If not there's always another con somewhere / sometime or some dress up event : D
