I think it's a great idea but I just hope the person installing it won't trim the wires really short.
Yeah, you either have to sacrifice the pickup cables or have loads of wire crammed under the pickup, with a couple of flimsy little wires running from the PCBs to the controls.
It just seems a bit fragile and finicky to me. And (forgive me for saying this...) not very rock'n'roll somehow.
