If you split a 4 wire double coil to make it sound more like a single coil, what is the best way to wire it. My diagrams say parallel?

I want it to be a dual coil as it was intended, but I want to use another 2 or 3 way switch to also get the best single coil sound that I can out to it.

I have a bunch of wiring diagrams, but I wanted to hear some opinions.
