And it makes the nice and tiny test-environment a lot less nice and tiny ;-) Anyway the scenario made me google a little bit. e.g.: https://www.yepkit.com/products/ykush is what I stumbled over. Add a RPi to it and you have IP-controlled USB-power. (Guess I have to order one to play with ;-) )
On the other hand iirc the Broadcom-SOC found in the RPi has a hardware-watchdog the linux-kernel has a driver for. So you might consider going for SBD (no shared disk) with watchdog-fencing as well. But that would require you to add a 3rd node (or some kind of shared disk).
