Cozy wings stiffness

Can the wings on a Cozy be made stiffer? Would this have an implication on the aerodynamics of the craft?

 

Surely the more rigid the wings, the better the aerodynamic capability?

 

Obviously the wings cannot be inflexible or too rigid, as turbulence and other airflow effects would damage the structure of the craft if the wings didn't move at all.

----> Sure they can. Change everything to carbon and they would be stiff as boards.

----> I'm sure there's a benefit, but any benefit would be sooooo small as to be barely noticable in normal flight. Stiffer wings might result in better roll rates. We've seen this on the Berkut and many believe it rolls faster because of its stiffer wings.

I don't see that that obvious considering If the center spar has equal stiffness.

The load paths come into question if you don't increase stiffness all along the aircraft or at least take that in account when increasing the stiffness of one part.

Basically it is not even that complex if you are aware what you do and know how to do the math for basic structures.
