I think it is simpler than you put it.

Koz hair in animation, um, .....  it is not a dynamic hair so I expect you do need to pose the hair in each frame of your animation, mostly so that it doesn't pierce into the clothes or her body or face etc. 

I don't think the Koz hair does upside down with its default set of morphs.  For that you would probably need to figure out an alternative.

Can be done with some elbow grease.  Or was that not the question you were asking...
