Default Flair SE5a concave convex profile

Hello, sorry my english!
I'm building a Flair SE5a, I'd like get a concave convex profile modifying the same original ribs.
I do not want use a RAF profile, but just get a concave convex profile.
With semi-curved squares, I managed to get a curved line........It might work for you? changing the center of gravity or wings incidence?
Here the picture of the original rib modified

I see no reason why it wouldn’t work. The original CG and incidents will be fine. The model was designed to have a fair amount of positive stability as is. This means it will trim at a certain airspeed and climb with the addition of power. Your modification will add to that a little. If you find it too much, you can add a little down thrust to help compensate.

Thank you for your positive response.
As you can see i didn't draw an accentuated curve!
