Whatever's going on, I don't think that's it.

Cowls (which are incompatible with hats for any race) don't hide Viera ears.

I think it might be to do with how their hair is modelled - possibly with whatever underlying issue apparently stops them from being able to share designs with the other races, but also that they might not have been built to turn off the upper part of the hair when hats are equipped. Some of the fluffier Viera hairstyles would probably collapse down rather oddly.
