"Three Way" Blend on front corner of car, a better way?

[SadSack]

Hi, I design and make thermoformed RC car bodies. On a few replicas (I usually just go by pictures) I've had trouble with the front hood/fender/bumper blend because there is a hump on the fender. Hopefully a few pictures are worth a thousand words. I have probably 40 features to define the basic shape, but then a whole bunch more to get it so I can blend in the bumper smoothly. I'm hoping somebody can suggest a better way to think about how this should be designed or other examples of weird blends like this.

Thanks

And a few more to finish it up.
