Essentialy, each 'coil' is a 4-wire twin blade humbucker. The Neck pup is just a sngle 'coil' and the Bridge is two side by side. You can run the blades in series, like a normal humbucker, in parallel for a thinner brighter sound, or even spplit them down to a single blade to use as a more traditional single coil. It all depends on how they sound split and across the different configurations.

With two On/On/On mini-toggles you should be able to do:
Bridge - Both coils / one coil / single blade (of one coil)
Neck - Blades in series / blades in parallel / single blade

That would give you a lot of different sounds across the two pups and you can just use a standard 3-way to select them. But, you don't really know which options 'work' for your build until it's built and tested. So, the best you can do is research the different configs for those pups and decide which sounds you want, then you can work up how it can be wired to achieve that.
