For that I'd have to get to downstream wires, either get the current relay
in the wall or splice wires out to an electrical box. If I tried it at the
breaker, the heater kicking ON would cause the relay to turn ON, causing the
heater to go off, and back and forth. At the breaker, I can set it to turn
the heater OFF at 14A and not kick back on until it's below 4A, the 10A that
would allow my heater to run on reduced power, around 8A.

Use a timer relay triggered by the current sensing relay.
If current is too much, switch off heating for XX minutes.
Problem solved.
