I'm just going to keep suggesting that a third clan of Elezen or Miqo'te would be better, especially if hands and feet for 'Viera' will be human hands/feet (as that really does make it sound like all you want is the rabbit ears, hence why Lambdafish said "So what that boils down to is you JUST want the ears"). Why terribly recycle a race (again) when you can add onto a current race and make them more appealing for others?
