Have you tried shielding yet? That might be all you need, or you need more than noiseless pickups as the rest of the guitar can have problems.
Verify you have shielded cable to the jack. Cloth covered wires might be vintage but they give you vintage noise. Twisting the wires does nothing, or we'd use twisted cable from the guitar to the jack.
Full cavity shielding with continuity between the pickguard and cavity shields to give you a full cage. Aluminum duct flashing tape works as well as copper for a low low cost, use a meter to verify continuity as you put it down and bridge any spots as needed.
Pickup bobbin shielding. Like chrome covered humbuckers and Tele neck pickups. Modern computers and cell phones make a lot more noise than they had in the fifties.
I've lined the inside of Strat coil covers before, you need to be careful not to cut or short the wires and verify a jumper connects them to ground.
Look into a dummy coil with a push pull tone pot switch. Get a Squier pickup, remove the bar magnet and the slugs to use the coil to cancel noise.
Those are the areas to focus on before going with noiseless pickups. You may not need them or not like the tone as much as your current pickups.
