Stamping passports on entry and exit is not something they do for fun; it's international legal practice in order to record your entries and exits.
As such, while a "low-risk" national could possibly convince, say, a French, Greek or Italian border officer not to stamp them, the person could be in deep trouble if faced with an in-country police check.
So no, this is not a practical solution.

A gap in the stamp history can simply not be used as an indication that the passport holder has been anywhere specific.
