I have the ability to pull something like this off easily, but I'm not convinced it would be worth the expense. I see a lot of potential with an Oobi-style scenario, though...
Don't sell yourself short. There's a dearth of new ideas in the vid biz right now and it's kinda frustrating that everyone is screaming for something new, but the market won't support experimentation. And that's a shame.
Personally, one of my favorite mainstream clips is a Japanese commercial with a horse puppet tickling a girl's feet. The idea definitely has merit.
And I've already got a zentai suit, so there's that.
