That's not going to work, Baja. Active Semblances are fueled by aura; if he runs out of aura he nothing left to fuel it, so he would no longer be able to use his semblance. It would simply cancel itself out, like when Sun ran out of aura and his semblance cancelled out.

Basically, if he's stuck in an intangible form because he ran out of aura, he's never going to turn solid again. His semblance drains aura as fuel, he has no aura so he has to wait for it to refuel before he can turn back solid again, but because he's intangible any aura he does generate would automatically be drained for the semblance itself. He'd be in a never ending loop, stuck as a permanent ghost until he dies of starvation or something.
