Poses by their very definition is a position that a figure takes for any given situation in real or imagined life. So if we take that as a starting point it seems likely that multiple persons will come up with the same pose for a given situation. So where does that leave us from a copyright point of view and legalities of doing what you suggest, I don't know is the answer but I know someone who might, I'll be back! thefixer, poser coord.

Injustice will be avenged.
