Dave, Just noticed another strange assumption in your arguments. I don't see how increasing AR changes W/L. It is constant unless you want to account for mass changes due to AR changes, which is true in reality, but again for a fixed span the weight of the wing is usually proportional to the wing area, therefore W/L will actually decrease for higher AR (smaller wing area).
