i assume you'd be putting p90's in? there aren't any other pickups quite like the blueshawks, which are p90 size but with magnetic polepieces like fender singlecoils. the dummy coil is only there to kill hum, but it also reduces the treble content, if you can live with a little hum p90's have a fatter sound anyway so you could just disconnect it. although if you leave it in the circuit it should work in pretty much the same way as with the original pickups,
i have to ask, why do you want to change them? i think they're great pickups, a fairly unique sound, like a fat tele or a fendery SG. it's a great little guitar too, i was sad to see Gibson discontinue it.
