The other is to cut about 6" off of the inboard side of each aileron for flaps and use the torque rods to move them, then run the ailerons with either a servo in each wing, or one servo in the middle with Nyrods running out to the ailerons.

In either case, I wouldn't extend them until I tried them out first. As was pointed out earlier, the outboard end of the aileron does 90% of the work anyway.
