Passive pneumatics and 12 motors?

The following question is based on the premise that a reduction in total number of motors allowed when using pneumatics assumes the actuators are being used to deliver a force on a load as an alternative to motors. If a pneumatic system installed on the robot is passive (not controlled by the cortex), can a team still use 12 motors?

Example: A passive pneumatic system that consists only of a tank(s), hoses and cylinders acting as dampeners or shock absorbers in a closed loop. The system has no valves or other cortex-controlled devices that operate the cylinders or manipulate the passage of pressurized air in any way, shape or form.
