Yeah, I don't know about the nude bit, but maybe we could get ... less.... clothes on some models.
Mainly I figured that there is a few models who have done this before to do the more complex/longer poses and then grab volunteers from the crowd for gestures and short studies.
Maybe it could be slotted as a rather long running panel over in creation, and then subdivided into specific studies... like gesture, hands, feet, and realism to anime... those kinda things.
