Default Thermostat question

On a 2002 Trailblazer does anyone know or have you ever heard of taking out the thermostat and just running it on the housing? Is this possible?

No that will cause it to run too cool and will eventually clog the catalytic converter and then you got big $$$$$$$$$$$$$ to fix .

You need a restriction so the coolent has retention time in the radiator
