At this point, if it were me, I would draw a line down the center of the length of the leading edge. I'd use a sanding bar and bevel the LE, leaving the line as the pivot point.

The aileron looks to be built per instructions, and Bax states that it will provide enough aileron movement.

If it doesn't, lispro can cut off the leading edge, and modify his ailerons to mimic the construction of those that I posted above, or follow your suggestion.

Your way may be a little easier than mine.
