I was asking.... whether your diagrams would work, as is, if the bridge was also a humbucker.
Yes, the diagrams and switch don't care what kind of a bridge pickup you have. The switch only "sees" the bridge pup's hot lead, and the switch will work to get the combos listed just as you predict, with the coil-shunt only affecting the neck humbucker.

... which of the coils would be active as a result of the coil shunt...
The way I have them drawn up, they shunt to hot, leaving the screw-coil active in a Seyour Duncan humbucker. Since I haven't found a way to shunt them to ground using a 4-way, you could simply rotate the pickup on the guitar to make the screw coil either the "inside" or "outside" coil.

Or, you could get a bit goofy with the leads to change which coil is left on. I'm just using the simple S-D installation stuff as an example.

A thought: S-D pups are out of phase with Fender pups, so with a Fender bridge pup, you would have to wire the S-D neck humbucker with GREEN as its hot (to the 4-way) and BLACK as the ground. In that case, with this scheme you'd get the slug coil left active.

Remember, different pickup manufactures use different color codes and different construction, so don't just use the colors I used UNLESS you have a S-D humbucker. For another brand of pups, the end result of shunting to hot may be that the slug coil left active. It varies, brand to brand.

would the 4-way switch be capable of this arrangement (swapping the first two):

1. Neck humbucker shunt
2. Full neck humbucker
3. Full neck humbucker and full bridge humbucker (in parallel)
4. Full bridge humbucker.
Yes:
