I am sure you have thought of it before, but it is very likely possible to fit the wing of the N/A crossfire although, not without some intensive work... The hardest part would probably be making it deploy... and having it deploy at the right time... if you do not want that you can probably just fit the N/A wing without having it deploy... ever... probably without much trouble... regardless the path you choose all seam rather difficult and inconvenient... unfortunately there is just so little aftermarket and fitting a new functional custom wing is not going to be cheap.
