No way. The only unique things about the Viera really are their ears. You argue horns in the game as saying Au Ra have horns. They also have scales, tails, unique mouths, and unique eyes. So far all we have really seen about our bunny girls is that they have ears. No special foot pose outside their starting armor, no tails. Adding Viera ears to the shop so anyone could use them would take away the whole identity so far for them.

You guys just need to wait to see if they eventually add Male versions and in the meantime, stop trying to force obvious alternatives.
