Viera males should be smaller like Au Ra females

[Agaziel]

Doesn't Male Au Ra already fit that? They are tall with athletic bodies with very manly faces that protect their tribe and are very agile because of all the hunting they do. Then again everyone is agile in this game. A Lalafell can go stand off against Roes. Not to mention that Roes can be a dragoon with dragoon jumps and flips.

And? You have lala equivalent to gnomes and you will have dwarf with a similar appearance to lala.
But I could give you the same narrative don't you have slim and small size males in game like miqo-te.
