The lowered aileron is a flap, and just adds camber to the wing which will probably* increase the stalling AoA of that part of the wing and delay the stall.
If the stall has progressed to a wing drop I would suggest that even if you reckon your aileron isn't as stalled as the rest of the wing (which is a big if), then the rapidly increasing upward flow because of the drop will be pushing it past that point pretty quickly. A flap is not just a flap when it's hurtling downwards at a great rate, surely.
