In a high AOA situation it is perfectly possible to induce an asymmetric stall on the wing you actually want to go up. It's not just the aileron that will stall, but when the angle of attack is very close to stall onset it will sometimes cause the stall state on that wing to kick in a little earlier. Most interesting effects can be noted on twin-engined turboprop aircraft that experience an engine failure and require some aileron input to fly straight and level. Slowing down towards (or even past) blue line speed and applying more aileron will easily lead to a situation opposite of what you are trying to accomplish.
Re elevators: since the horizontal stabilizer on all aircraft has a smaller or even inverted camber when compared to the main wings, this surface cannot be stalled before stalling the wings first. When the main wings have reached a stalled condition, the natural behavior of the aircraft will be to pitch nose down. Unless of course you are flying a poorly designed swept-wing aircraft where the wing tip stalls before the root, which causes the lift center to move forward and cause a pitch-up motion.
