A number of years ago ArtieToo posted diagrams for a coil swap mod. Granted, it wasn't inner coils and outer coils, but instead swapped the slug coils in series. If you rotate the neck pickup you accomplish moving the coils without too much fuss, but it's still combining a screw/slug and not the screw/screw and slug/slug that you may have intended in your first question.
Add in a second DPDT and you can have a split mode (mine are split to slug coils). I have two guitars wired up this way - an Epiphone SG was a C5/AP2P, and a Dean Soltero with a Dimarzio Super Distortion and 36th Anny. The only thing I wish I had was outer coils in parallel in split operation.
Search for "Coil Swap Mod" and it shouldn't be too hard to find, that is, if the diagrams are still live.
