It works fine on the coil you normally shunt to ground for coil splitting, but wont work for the other. The first coil has the start of the coil wire grounded, the finish is tied to the finish of the second coil in the middle of the two, and the start wire of the second coil is the hot lead. Both coils are wound the same direction, normally ccw, and by reversing the leads on the second coil you get the reverse wound part of the RWRP/humbucking equation. The other half is of course that the ccw coil sees the south side of the bar magnet, the cw (reversed ccw) coil sees the north side and you have the reverse magnetic polarity that completes the humbucker. When you split the humbucker you are shorting the first coil, but as you shunt the second coil you also affect the first, this is your standard master volume control for the whole pickup. If you had the coils in parallel instead of series then you could do what you propose, treating each half as an individual single coil, but you'd want each coil to be wound a lot hotter to make a good sounding pickup, or a much stronger magnet. It is probably worth considering to have the master vol, first coil dial a split setup per pickup, or to get pickups that have a voice that you like and experiment with a PTB tone control for more tone manipulation.
