It was actually relatively simple but detailed.
1) Extract the Edges of the surface.
2) hide the surface.
3) Use the Point on Entity function and place Points on one side of the extracted shape, in varying intervals, leave the ends alone. You definitely need more than one or two for this shape and I avoided areas where the topology of the edge changed drastically.
4) Select the opposite side of the contour and the points that were created in the last step
5) Use the Point Perpendicular command so that you have points on both sides of the contour.
6) Join the Points together using the Line Join command. (NOTE: select two perpindicular points and select the menu option. select the next two and press F4'repeat last')
7) Use selection criterium to select and delete the Points only. (Edit -> Select)
8) Use Point on Entity to create new points in the middle of the lines created in step 6.
9) Rotate the Points around X.
10) Move to Z the points (all to Z0, not relative).
11) Select the points in order.
12) Spline the Points with the Interpolated option (.0001 accuracy).
13) Use Extrude Curve to create a Surface out of the Spline.
14) Rotate the new Surface back so that it is in the proper orientation.
15) Unblank the original surface.
16) Position the surface extrusion so that it falls in line with the part in X and Y (Z should be fine unless you didn't use enough points).
17) Boolean -> Union the surfaces together(this creates an edge in the middle of the original surface).
18) Unstitch the surfaces and delete what you don't want.
Hope this helps.
