I've also considered that and should probably do it. My post-cat is a heated 4-wire sensor.
My reason would be a little different. A while back RH77 reminded me that extensive use of EOC (engine off coasting) can cool the 1-wire 02 sensor and push you more into open-loop conditions. One that stays heated would be immune to EOC.
