If I try to use a "ruled surface" using the outermost splines, gmsh ignores the peaks in the interior. If I try to use sub-segments of the splines, I can't with out splitting them. But when I split the splines using break points, they become straight lines instead of curvy.

Gmsh's internal CAD modeler is very rudimentary. For complex surfaces you should probably create them in a "real" CAD tool (e.g. FreeCAD), export as STEP, and mesh in Gmsh.
