If you don't mind, I'll take a stab at some feedback.

Variant 2 sounds the most likely, maybe with practice she could achieve Variant 1.

I wonder if the dust would be finite though...from what I understand, it can be consumed like any sourse of energy. Just a stray thought.

I like the idea of Divide Wind, but the thing about Aura, is its basically a MP bar, HP regeneration, and Energy Shield all in one. But when its used up. Its gone. They cannot activate their aura in any capacity. Thus, something that would use it all...well, its nearly suicide. Its also very finite, unlimited aura would make them basically invincible. Not a bad thing, though, a short window is perfectly fine. I'm concered with how her Aura is more powerful the less she has of it. It doesn't really make sense. Logically, the more Aura she used the stronger the ability would be. Canon-wise, I would compare it to Yang's Aura (which would make sense, as they are both the berserker/brawler type) but hers worked by converting the kinetic force she takes into added strength. I don't think she should be able to transfer her Aura to someone else, but thats more up to you.

In summary, the idea is solid, but it may need some tweaking to work.

Just my two cents. Take it or leave it.
