However to answer the original question¡
You SHOULD be able to wire up an auto-reverser from DCC mains (or use an auto-reversing booster) to feed several PSX (or other brand) electronic circuit breakers that feed several CB protected districts inside a common reversing loop/section. Just make sure each of the circuit breakers react faster than the auto-reversing controller and that there is an initial section of track at both sides of the single AR loops district entrance wired before any CB protected track.
However I¡¯m not sure you would want to do that as the troublesome areas will be at the turnouts and it sounds like costly non-effective overkill.
