Since the wing is set up for a metal rod, there is no pocket for a plywood joiner. It may be difficult to try to remove some of the dihedral. I guess you'd have to add some wedged ribs at the root ends of the wing and carefully bend the metal rod to fit the new wing shape?
Others here will have the correct information for you.

It is quite easy to do by bending the metal rod. Yes, you have to fill the gaps.
The more difficult & time consuming method is to cut slots in the end ribs for a wooden joiner, but ultimately, that method results in a lighter wing. As I said -- your choice
