Sorcerers Apprentice

Depends on whether or not I would have allowed a winged aasimar in the first place.
No, I would not as there are no Aasamir in my campaign setting. However, if there were, I would allow it.
I'll be the Debbie Downer and say that I'd be inclined not to allow it. The player knowingly and willingly made a choice to not have wings and when it mattered decided at the spur of the moment to change his mind.
My problem with this issue would be three-fold.
First, there's no documentation that Aasimar can re-grow or regenerate wings which have been severed or scorched off.
Second, the sudden sprouting of full-strength-wings regenerated that quickly?
Third, the PC can now use these wings, without any
adjustment period, or practice?

Yes, but not as physical wings, rather as wings made of that divine energy, which then dissipates once the need for them is over, perhaps to return in the future if the situation is again dire enough to need them.
