Hi Scott,
Here's a video of how I made the example.

In the video, I talked about a poor decision in my model to create a "radiused curve" in the originating curve, instead of a hard edge.. This can create problems later.

I tried to make note of showing how the red curves from your original model are trying to mimic what the fillet creates. Trying to hand model those would be hard. I suppose the trick is to figure out what the original shapes and orientations are that would have the fillet edges match a "picture" or somthing...

I also think that if you are trying to "totally match" from a picture, you may get better results by using a revolove, instead of the blend i use, on the initial pod shape.. Revolving half of that curve, then turning on control points will allow you to change the shape in a way to match your base curves you started with...
