I'm embarrassed to say it, but this I the first time I've figured out how to use the Blend tool, it works great for this application. I set the snapping to surface and drew a line along the profile to form that edge. It doesn't follow the surface perfectly but close enough that the trim command cuts a nice clean edge. Then I used the blend tool and that got me most of the way. I turned on the surface points and drew a swooping line along the flowing ridge of points, skipping the ones out of alignment. After that simply snapping the surface points along the smoothed curve cleaned everything up in that compounded area.

Thanks for the help, this is excellent!
