Curtis Novak makes some humbuckers that fit in the Jazzmaster route that with a "dial-a-tap" (variable) coil split setup on the second set of pots on the guitar can still sound like a Jazzmaster. But I doubt those will nail the Jazzmaster tone. I have a pair of Seymour Duncan Antiquity 2 pickups in mine (I can't recommend them enough) and they are, to my surprise, not that noisy if at all. Just make sure you shield and ground everything properly - I used a Rothstein copper shield for the pickguard, and then copper tape in the cavity. Sorry, I know this only partially if at all answered your question!
Generally - there are noiseless Jazzmaster pickups, which are stacked humbuckers, and thought to be lifeless sounding by many players. The Jazzmaster is very close to the P90 tone, and a HB just doesn't to it justice.
