You're not as far in the solve as I was thinking. You need to figure out how your edge swap alg works. I don't know which one you're using. I like d R F' U R' F d' while having the edges swap on the front face. d is one of the middle layers. You can just as easily do d2 on the ends of that alg to swap edges on the front-right edge and the back-left edge. Assuming you haven't turned the cube yet, flip it so it the white is in the front and the green is to the left and try the alg I gave with d being the 3rd layer from the bottom. It should match up inner edges to the Red/Blue center edge piece, and the two inner edges by the green/orange center edge will be opposite colors than the center edge. Playing around with this alg you should be able to get to the point where all edges are along their correct edges but may be flipped incorrectly.

I apologize if I thoroughly confused you.
