You need to define your hybrid goals. Mismatched coils don't cancel as much treble, or add as much midrange as matched coils do. Some single coil sound comes thru, the bigger the difference in coils, the more single coil sound leaks out. So, where do you want the added high-end and clarity, neck or bridge?
I've made hybrids to get what I want for my neck HB tones: sharper high-end & no mud. To do it I pair two PAF coils, one from a bridge PAF and one from a neck (same model or mix and match). That's enough difference to be easily heard (about 10%). I personally see little point in pairing up two coils with similar resistance (like two neck PAF's). Since manufacturers won't reveal their winding secrets, we don't know how much alike, or how different the winds are on various PU's. You could pick two coils that have almost the same wind, and if the resistance is similar, what's the point? At least with different resistances, you know they will be unmatched and the magic will happen. I can make a '59B/'59N hybrid, add a warm magnet (A2 or UOA5), and it will have more high-end than a stock '59N. The warmer magnet also gives more texture, and doesn't have the bassy A5 low-end either. That's what I'm after. What are your goals?
I've also done some bridge hybrids; you don't need the huge coil difference of a '59/Custom (7K vs 4.2K). I think it's more interesting to make hybrids with less of a difference, and use a warm magnet.
Two DiMarzios that have a big difference in coil resistance are Fred & Bluesbucker, and those coils are good for making hybrids with.
