Look back to the Pou de Ciel of the late 30's. I don't know if you could classify it as a wingeron but the entire foward wing, it had two nearly the same size, pivoted at the CG, to change the angle of attack for climb and descent. No elevator, just a rudder and putt, putt engine. It was a homebuilt and did fly with a man in it. I believe the designer was a Henri Mignet and he tried to revive plan sales post WWII. I don't knowif he got any takers. Pou de Ciel means sky louse or flea. It was often referred to as a flying flea. Maybe not wingerons but a wingevator. You can add that to your list of wierd aircraft terminology.
