As in 2 full p90 coils wired together to humbuck?
You could wire any 2 p90 guitar to do that.

My Casino has one of them RWRP so they are humbucking in the center position.
But those would be in parallel.
OP didn't say had to be series.
DiMarzio has a Super Distortion in soapbar format, if that counts.
