I cannot imagine any requirement for more than one engine (with or without reheat) to be run at full power when parked in the detuners. Thus there would be very little chance of exceeding the brake torque limits.
Brake torque us only one of the things you have to think about when running at high power.
Consider running an engine on one side with all the others at idle or even shut down, what do you do when the aircraft starts to slide sideways?
The engine run drills call for "balanced" power. What this means is that you have to balance the power which means running the opposite engine at high power also.
Been there, done that!!
