IMHO I think it is unlikely, since carbon fiber is pretty stiff stuff and the airfoil of the rear wing has a significantly higher second moment of inertia than say the flimsy body cover of the Porsche which means its much harder to bend.

Carbon isn't as stiff as you assume. If you build it right, depending on weave, and orientation, it can be pretty darn flexible.
