Over Voltage with New Battery Disconnect Switch
Here's another way to kill all power to the engine. If that's the sole intent of the rule, then it will work. If the goal is also to kill all battery power going forward, then it won't do. My impression was the starter cable does not have to cut off by the switch. If so, then probably the alternator feed can stay hot as well.
^This^ is basically the same as the intent in the diagram below from post 1.
The way I drew it, the regulator should work fine and the kill switch will stop the engine from running as well power getting to field.
The original black wire from the alternator to the main junction can be hooked up to the starter relay or the junction where the 1 AWG wire terminates. That would then provide two parallel wires from the fender to the original main junction.
I've seen a number of cars using them, mounted on the battery case and other places. So probably yes. Probably depends on the details.
