BAD idea. If someone flushes a few times, you'll get very hot water
being passed over the wax ring and cause melting or significant
softening.

Tempering valves only add enough hot water to get
somewhere near room temperature. Nobody's suggesting
replacing the cold-water supply with pure hot water.
