As long as your electrical system can handle all the fans without overloading the alternator, you'd be OK with that setup. I'd suggest a progressive fan strategy, maybe running one fan at thermostat opening temp, and kicking the second one on 20 degrees above thermostat temp. (180 degrees for fan #1 and the trans cooler fan, and 200 degrees for fan #2 if necessary.) You can get thermal fan switches and relays that can be set to a wide range of "on" temperatures.
