Hog-Bipe Flaperons
Since you have the capability and the interest, go for it. The Hog Bipe should be forgiving enough to let you do most anything. Just do it at altitude just in case the big Oops happens.
Look at various settings and see what happens. Start with the maximum deflection so that you will definitely see some effects. I haven't seen any data on the subject, before my time, and would be interested in the results.
Let us know what happens.
