yes but… disconnecting two plugs and then connecting them to another effector (with for example a different hotend mounted on it) is pretty much the same time wise as disconnecting 1 plug, without the hassle of a different PCB
As you are already using 397mm rods, and even longer ones might be better when you change to linear rails and move the attachment points closer to the towers, it's probably best to go to Haydn for custom length rods.
I was also thinking if it would be viable to divide the temperature curve (R:T) into ranges and have the software adjust the temperatures reported by DWC in the lower range to better reflect actual temperatures (while relying on actual readings in detecting faults). Not exactly necessary but there's something about those incorrect readings on my all-powerful control interface that rub me the wrong way.
