I have successfully imported Victoria 8 into P12 but as mentioned above the hassle outweighs its usefulness.  Clothing, hair, and poses need to be treated the same way, and all the figures and objects will require extensive Material Room rework for the textures to work with either Firefly or Superfly.  If you don't have DSON installed, you will need to explore another alternative for importation, perhaps FBX.
