If the added material is put on the inside of the aileron (behind the existing 3/16" piece), you can sand a harder angle on the front piece of the aileron without increaseing it and thus not sticking out past the trailing edge of the wing. I'm still not convinced that you cant get close to the throw you are looking for by tapering the existing 3/16" leading edge.......Gene


Biker beat me to the same answer......
