You could get a humbucking pickup, most pickup manufacturers make them. Some are bonded into the case though, so you may not able able to swap. If you were feeling adventurous you could try a Lace pickup for you noiseless needs.
As for wiring, some are four conductor (in which case you just solder two wires together yourself) and some are two conductor (hard wired in series inside the pickup). It's no harder to wire in, you're soldering two wires into your pre in both cases.
