This would be cool and I've often thought about posting the same request. However, while PT's, M16's, M3's, Jeeps, and I belive M8's (armored car and not a tank) all have gas pedals and thus a seperate throttle from the steering wheel (or joystick in our case) I'm not sure that Tanks, and LVT's did which would make sence to have these vehicles throttle tied to the stick.
