Several years ago a Sonerai lost a wing making a high G turn during an
air race conducted by the Formula V Air Racing Association, resulting
in a fatal crash. The Formula V group then hired a professional
aeronautical engineer to conduct a design study and and a wing
strengthen modification was the result, which was made mandatory for
all racing Sonerais. You may wish to contact the Formula V people for
details : http://www.formulav.com/

I think this post is very telling, in why you have not had any other posts
answering your questions.

It is a very risky procedure, to start major design modifications, or
substitutions to a critical structure, like a wing. If it fails, you are
probably dead.

No one here is likely to be very comfortable having any part of advising, or
being an accomplice of such a substitution of such magnitude and scope.

So although I think it is a bit of a cliché, If you have to ask, you don't
know enough to be asking.

My best advise? Build it as drawn, or find a plan that has what you want,
in the original design.
