Yoshi already said that Viera will be given "some" of the shared hair styles and Hrothgar will be given more Hrothgar only hair styles and faces sometime after release.

Funny, on paper the Hrothgar clearly have a more severe problem in this regard but in practice the problem effects Viera the hardest. As in many Viera I see easily look alike were as the Hrothgar's fur/ fur patterns and skin color makes them look so different even though like 80% are using the same face.
