so the tow package never came with the 850w fans interesting, i dont tow but many people here do tow with the JL and some people paid for the tow package on the JL, i dont know why you would say that it was not built for towing but anyways, they both use the same radiator the only difference is the fan, so a 850w fan swap should be able to give you as much cooling capacity as the gladiator.
I think you are on to something here. You are going to be much happier with increased cooling capacity than with a colder thermostat. Note the Gladiator grill is also designed to allow more airflow than the JL grill.

A diaphragm-type thermostat controls the operating temperature of the engine by controlling the amount of coolant flow to the radiator. The thermostat is located inside of the thermostat housing and is serviced with the housing as one unit. On all engines the thermostat begins to open at 88°C (190°F) to allow flow to the radiator. The thermostat is fully open by 100°C (212°F). This provides quick engine warm up and overall temperature control. The same thermostat is used for winter and summer seasons. An engine should not be operated without a thermostat, except for servicing or testing. Operating without a thermostat causes other problems such as longer engine warm-up time, unreliable warm-up performance, increased exhaust emissions and crankcase condensation. This condensation can result in sludge formation. The wax motor is located in a sealed container at the spring end of the thermostat. When heated, the internal wax expands, overcoming closing spring tension and water pump pressure to force the valve to open.
To be correct, water pump pressure has nothing to do with the opening of a thermostat....just the expansion of the wax. You can boil water and test a thermostat for movement.

Just posted the section from ShopKey regarding the Jeep JL.
