the only way I can see to do it would be to wire each coil with an on/off switch in a funny coil||(coil+coil)||(coil+coil) configuration. But that would be a pain to switch on the fly.
First of all i have a few technical questions. What guitar do you have? This will let me know what options you have as far as hardware installation. What pickups do you have? This way we can make sure they can be split.
Also a comment, having the most versatile wiring isn't always the best option. For example, the middle humbucker will sound roughly the same split to one coil versus the other. It would help you greatly in the long run narrow down what you actually need rather than simply add more switching options to your instrument.
