Okay, I've run into those before and those don't really have a typical Strat sound. If anything they're closer to a P-90, or a Firebird but not hum-cancelling. A JB won't overpower them as long as you lower the JB a little bit further from the strings than usual. That said, the SD Hot Stack (
not Hot Stack Plus) single coil will match in output and tone. It too has more overall output and more of a mid focus, like those Dragonfires, and also uses a ceramic magnet for a similar pick attack and an even magnetic field, but of course it's also entirely hum-cancelling. It's often used in the middle position of HSS guitars because it's such a versatile fit balancing between humbucker and single coil tones, but it works great as a bridge pickup in its own right.
Prince's guitarist in the 80s, Wendy Melvoin, had a couple of the Telecaster bridge Hot Stacks in a Rickenbacker guitar (yes, a Tele
bridge Hot Stack as a neck pickup), specifically because Prince needed her to cover a huge variety of sounds, from humbucker to single coil and from totally clean to massively crazy distortion, and there was nothing else that did that middle ground better.
They can be hard to track down as an individual pickup, though, since they're not terribly famous and a lot of shops only stock them as a full (and expensive) SSS set. A Hot Rails can be found much easier, and a Hot Rails wired up parallel sounds very similar, just a tiny hair warmer. The Vintage Rails is also in a similar spot (wired normally) if you don't want the extra warmth of a parallel Hot Rails. (You'd think the Cool Rails would be an ideal middle ground, but that pickup is
very low output when wired parallel, and a touch muddy, which is why the Vintage Rails exists; the Cool Rails and all the 'little' humbuckers are best for getting actual full humbucker tones.)
There's also the Hot Stack Plus which is a similar idea to the Hot Stack but with individual pole magnets, which causes a more uneven magnetic field and a more classic Strat sound. In this instance I would expect that pickup to be too thin to match with the middle and neck pickups; it's beefier compared to normal Strat pickups, but the bass is weak compared to anything with a bar magnet.
