I suppose my thought is one of simplicity... the current setup still requires pilot action during/after the flight to set the switch to "auto" so the thermostat can do its work. Having a timer that you quickly turn/set on shutdown could accomplish the same task and eliminate a bit of complexity (don't need the thermo-switch), as well as provide a known value for how much your battery will be discharged. I'm not saying that the current setup is bad by any means, I'm just looking for some info (how long does it take to cool down?) to tailor a potential alternate solution.
Another option, depending on how your master switch is setup, would be to wire the master such that the circuit to the thermo-switch is closed when the master switch is in the "off" position. This could eliminate some of the human factor from the operation of the pump. I used a DPDT ON-ON-ON style switch for master+alternator control and I believe this can be added to my switch.
