OK - if you have leeway with the section curves for the wing (as I assume you do) you can do this.
I’d say if you make the outer edge of the wing surface a little taller, you’ll be OK. I’ll see if I can make something worthwhile later this afternoon.
Here’s what I get, working off of your starting point - I lifted the outer wing section to be a little taller and made the curve much simpler. It is copied to the root and lofted to get a simple clean surface. The surface is then extended outward and trimmed with the blend curve to provide an path for the edge surface to wrap around.
