Protoype Arm Models (custom)

As I have heard, the models from prototype cannot be rigged for Garrysmod. But would it be possible for someone to make custom arm models that resemble the shapes/weapons that Alex makes for combat (i.e claws, blades, flails). If anyone has the time, I think it would be interesting to have and to perhaps hack them with some civilian models, or maybe with the human hunter to resemble alex mercer.
