You might have better luck copying one shape, pasting it in place (found in the File menu), then modifying the new shape in areas where they don't need to be seamless. You can modify existing paths by keeping the Pen tool active and holding down cmd/ctrl to temporarily access the Direct Selection tool and the option/alt key to temporarily access the Convert Direction Point tool to modify the path to try to get it to align. I truly believe that the copy/past method would be easier though.
Thanks Chad. I guess I was hoping there was some fancy command I didn't know about, but this is getting the job done.

Well there are Pathfinder functions that can help you achieve congruency or puzzle-piece-type fit between objects, but their application tends to be rather scenario-specific, so there isn't much to be said about them in a general sense. You just have to get familiar with how they work and then apply "artistic mind" in finding ways to use them.
Illustrator's Shape Builder Tool will accomplish this. Existing paths could be copied and pasted into Illustrator, use tool, and pasted back into Indesign doc.
