I don't like it. Well, from a creative standpoint, it sounds pretty neat. But let's take a real life look at this: I'm an actress, in the theatre department at my school. I have a lot of respect for my teacher/director. When she tells me to do something, I do it. I've dropped/fallen as I purosely try to or on command. And it hurts if you don't do it right, or mess up. Sometimes it hurts if you do it right anyway, just by force of impact. Now imagine being in a big body suit kind of costume while being forced to fall like that. Even if you don't mess up, dirty or damage your costume, that's going to hurt, especially with the weight. It's no wonder they don't do it. I wouldn't.
