To be honest, I think you might just be ruining the look of your pickups, since you'd have to mess the black tape up. I think there might be very little audible difference by combining the coils, since they're almost the same. The 59 is 8.1 and the Jazz is 7.9, so half of that pickup would be .1K apart from each other.
The difference would be greater by combining low output with high output humbuckers. With the Jazz, I'm pretty sure you'd want to use 250K pots in a strat, and 300K pots in a Gibson.
