Not to waste the PC4, I have another couple super-low-draw devices connected to the other 3 ports.

Have you ever tested your setup ? I see how it can work and like the idea
I would just set the one port to 'On' when it looses communication, and have the other 3 to 'Off' so they don't draw down the UPS

Ah, this would also keep the Head Unit powered
Interesting ...
