Just wondering if the following is possible with a 4P5T superswitch;
-NxMxB -M+B -N+B -NxM MxB
Would I be correct in assuming this needs five poles? Everything I've tried so far leads me to think so.

Not sure, sydd, I'd have to sit down with pencil and paper But before I do so, does the order of selections matter?

This looks like a special-purpose wiring for someone who has other guitars to do the usual sounds?
I think it can be done too.
I'm thinking:
wire M- to B+ permanently in a series chain Have two superswitch poles going to hot output One pole to ground One pole on the N+, to connect it wherever it needs to go (output or M+)
To get the -M plus B, you ground the connection from B to M and take both other ends of the chain to hot

syddd- I think this does it, but let's get it vetted before you start wiring.

That looks like its all in-phase though? The OP has mostly oop sounds as listed.

John-
I took the dashes at the beginning to be like "tick marks" and not minus signs. Hmmm. I guess syddd needs to weigh in . . .

Would I be correct in assuming this needs five poles? You would not. You can get all five of those specific combinations with just four poles. The solution to this switch-puzzle isn't elegant. You'll have a hanging from hot issue in one or two positions. But if you're okay with that, four poles will get you there. (1) Since the Bridge pickup is used in every selection except one, you could connect its (+) end to hot (output). The (-) end of the Bridge is connected to one pole of the superswitch. This pole allows the (-) end of the Bridge pickup to be connected to ground in the two positions where the Bridge is in parallel. And it allows the (-) end of the Bridge pickup to be connected to another pickup in the to positions where the Bridge is in series. (2) Since the Neck pickup is ALWAYS out of phase in all three positions where it appears, connect its (+) to ground and its (-) to a pole of the superswitch. This pole allows the (-) end of the neck pickup to be connected to hot in the one position where the Bridge is in parallel. And to another pickup in the two positions where the Bridge is in series. (3&4) The each end of the Middle pickup is connected to a pole of the superswitch. It can be connected anywhere, in-phase or out of phase. Done! If it were me, I'd use Strat-O-Various version 2.0 as my starting point. guitarnuts2.proboards.com/thread/7826/guitar-wiring-tutorial-various-projectThat would allow the five combinations you listed plus as many as five more. But it requires a DPDT (either a minitoggle or a push-pull) for the S/P switch.

I didn't think a hanging from hot was needed in how I described it. But I subb'ed M-B for -M+B, since it sounds the same.
It sure is an unusual set of 5 settings though, and Id be interested to hear why they were chosen. Every other plan I've seen has also had most of the basic stock settings too.

John, I might be wrong but I think the way you described has hanging from hot issues in two positions. -M+B and -NxB.
But the permanent series chain of Bridge and Middle you propose is a superior solution. Just use Bridge (-) and Middle (+) as the series link and I think everything cleans up nicely.
It even gives -M+B exactly as listed. Although you are correct that -B+M would have sounded exactly the same anyway.

This is how I was thinking: And OK yes there is just one hanging-hot issue!, but not too bad, there are two other PU's in parallel to it.
