I didn't mean for this to sound like it was impossible. It's something I've wanted to do for a while now it's just a little more complicated than just dropping a couple pads and calling it a day.
Quite a few boards are getting overhauls this year, so I'll definitely keep this in mind and see if there's a good way to pull it off.
It probably wouldn't be a very popular decision, but if it were entirely up to me I would remove the LED and current limiting resistors from the effect PCBs altogether and delegate that task to the various bypass boards. This would put the LED in a standard location beside the footswitch on all layouts.... Then the SW and GND pads could be repurposed into VCC and GND pads.
