Since "they have to redesign EVERY piece of gear for m viera and f Hrothgar" keeps getting brought up:

Male viera use the elezen skeleton, that's it they don't have to work from scratch.
Miqos and female auras use the Hyur skeleton, Hrothgar the Roe skeleton which in itself is also the one used for Highlanders. Female Viera use the Ferm Elezen one.
They don't have to "redesign every piece of gear individually" the pieces are all here and have been used in this way since launch
