I figured that as long as I kept the area of the aileron the same as the plans show, I could adjust it's shape a little bit without changing the aerodynamics too much. I took it one step further, and made the outboard edges of the flaps and the inboard edges of the ailerons perpendicular to the hinge lines. I ended up with nice small consistent gaps at the intersections and the control surfaces do not interfere with each other as they go up and down like they would have otherwise. The plans show those two edges "in trail", or parallel to the aircraft centerline.
