Well, apparently it is possible to make a moonkin costume.

This one is sadly not pear-shaped enough, nor is it the right faction*. But it means that the idea is not that impossible. For the record, I have been thinking about making one of these for awhile now. I just cringe at the thought of how much *time* it would probably take. And room to make. And store the final piece. I think I would probably use hoops (like what you'd see in a hoop skirt, but maybe more than one- dunno). Would probably use LED's for the eyeballs, inset into the headpiece (maybe use egg carton cups to get an even reflective surface in the eye sockets.
