I don't quite understand why you mention incidence, as I was referring to the effect of changing AOA indirectly by changing the MAC. Let me explain a little further, and I could very well be wrong here. The MAC at the wing tips is a function of the airfoil and the deflection of the aileron (my assumption). UP aileron will shift the MAC upwards and therefore decrease the AOA of the airfoil at the tip. Am I on the right train of thought here?

Most times tip stall is prevented by twisting the entire wing. The tip section is at a lesser angle of incidence than the root section. So that being said I suppose that it would help sto some degree if both ailerons were tipped up slightly.
Please don't confuse angle of attack with angle of incidence. AOA is the angle between the mean aerodynamic chord and the relative wind.
