My thought? Since Aura is already going into the semblance, it would just use the Aura powering the semblance to activate the Dust involved - that way, there's no extra aura cost to combine Dust with the semblance (especially when using a semblance like Weiss', which provides some sort of visual/semiphyisical effect).

However, I have to say I think that thought is wrong - but it's just a suggestion.
