It's possible, but very impractical. Better just to stick with electronically actuated hydraulic brakes for that trailer.

Do trailer brakes automatically lock when the air lines have been disconnected?
Air pressure within the air braking system of a tractor-trailer (or large truck) is what prevents the brakes from being applied. The pressure of the air pushes back a large spring at each wheel. The large spring will apply the brakes when there is no pressure in the system. When the driver steps on the brake pedal, air is released out of the system and the brakes are applied. When the driver's foot comes off the brake pedal, air is quickly pumped back into the system and the brakes are released. Disconnecting the air line has the same effect on the trailer's brakes. Air is released from the system, and the brakes are applied. It is not the brakes themselves that lock. Application of the brakes causes the wheels to lock.

The tractor air control valve? Stops air from flowing to trailer red air line. Safety switch incase trailer falls off truck all the air will not go out the broken hose and cause tractor spring brakes to lock up due to low air. It can be tested by disconnecting red air line while trailer brakes air released. Air should stop at about 30psi I think.
