Single humbucker wiring options

I'm considering swapping out the single coil pickup in my Squier Bronco for a dual rail humbucker. This pickup presents a number of wiring options, as covered in this article:

So, if I forego any switching, I would hook it up in the default mode with both coils connected in series. Simple. Tone variation is explicitly dependent on the capacitor and tone knob.

If I introduce a push-pull pot, I would have one of 3 additional options:

1. Both coils in parallel
2. Split the south coil
3. Split the north coil

Question 1 - Are any of these variations useful on a Bronco bass?

Question 2 - Does a combination (stacked) potentiometer/multi-position switch exist that would allow me to select between all 4 variations?

Question 3 - If such a device as above exists, is it worth the added complexity?

I'm hoping someone has already researched this and has some real-world conclusions.
