I'm not sure. I just don't recall them saying this would be impossible. Frankly, it wouldn't make sense to me if it were about racial identity, considering viera are using midlander's set, and they are mostly all just general pieces; no real racial themes. This would probably be one of my most anticipated additions to the game. Many of the hempen pieces are great for many glamour combos.
I'll pass on the highlander hempen set. :p I think you should be able to use the au ra set, and the midlander set though!
I wish! I would still love to use the miqo'te hempen top without actually having to play a miqo'te. That'd be a dream.
