Gosetsu on the other hand is confirmed to be another subrace of Roegadyn by the developers. Granted we know his unique design is to make him stand out more, but it's no more different than what other important NPCs have gotten.
Hilda is really our only main go to for mixed races, as she literally has another races features on her model, in her case Elezen ears.
