Get a set of DiMarzio Ultra-Jazz & wire them in parallel.
The default wiring configuration is series, but that is where the top-end gets lost, because the coils in series will increase the Inductance, which lowers the resonant peak of the system.
Inductance is summed just like Resistance:
2 + 2 in series = 4
2 + 2 in parallel = 1
Inductance will pass low frequencies & block high frequencies
Capacitance will block low frequencies (DC) & pass high frequencies
the Resonant Peak is where those two meet for the highest output
A parallel split-coil humbucker will get you to 90% of the single-coil sound, & TBH in a band setting, no one will be able to hear that additional 10% the single-coils give you.
TBH I'm struggling with this dilemma here at home now & will spent a fair bit of time this weekend experimenting with stainless DR Lo-Riders on single-coils & split-coil humbuckers.
