Importing new geometry for player models?

Hi all,

I was looking into making modded players that use entirely new geometry, wholly imported models, rather than deforming or editing models that already exist in-game. I remember this wasn't possible with some earlier versions of NBA2k. Is it possible to import entirely new models for player heads/bodies using the Blender scripts and have them appear properly in game? They don't need to necessarily be animated or anything, I just want to know if importing the models is possible.

Thanks!
