Yes, but I worry about the weight downside. E.g., the wings might be stiff and notch-proof, but the wing roots will suffer more, to say nothing of landing strut wells. Also, because stuffing is 3D, the calculations change: moving from A4 to A3 increases the weight not to 200%, but 282.84%, assuming uniform density.
I have no idea when/if the weight penalty would negate the stiffness benefits, so Herky's project could be an interesting test.
