Alternative solution would be that people edit the DBC file rather than the model, unless there's custom textures involved, thus switching the model data and making it universally using only one model rather than two, but that's just my personal opinion right here :P
But on the other hand, that would make it impossible to use two model swaps, so...yeah.
