Would changing the thermosat temperature thermostat increase or decrease mileage? The amount of fuel is controlled by the ECU and once the car is warmed up, would +,- 10 or 15 degrees increase or decrease mileage. I am thinking that combustion could be a little easier, especially while the car is warming up, and it's such a small difference that the ECU might not go into limp mode.

When a gas car is warming up, they run in cold loop mode and run rich to warm up the car because the o2 sensors aren't working well yet,

So what you are saying is that the coolant won't help but increasing the efficiency of the radiator so you can block off the grill will? Isn't that the same as changing the thermostat?
