Protogen Options

Wondering what you all prefer: Do you think that Protogens should be their own species in the selection menu, or would you prefer having the ability to place the facemask over any species? 

Separate species means better looking model/blendshapes specifically for Protogens, where as generic facemask/etc will have to accommodate all types and probably not look quite as good in most cases. Planning on redoing a bit of the cybernetic arms and thought of this as an option, so I wanted to see what you think
