Trying to work out some odd split&phase wiring - is this even possible?

I've got a Les Paul with two humbuckers (both with four conductor wiring), the usual 3-way toggle and four control pots, one of which is a push-pull.

What I'm trying to get is this:
P-p down:
Bridge humbucker (both coils wired series)
Bridge humbucker (both coils, series) parallel and out of phase with neck humbucker (both coils, series)
Neck humbucker (both coils, series)

P-p up:
Inside (slug) coil of bridge humbucker
Inside coil of bridge humbucker parallel and in phase with outside coil of neck humbucker
Outside (screw) coil of neck humbucker

So one pot needs to:
Split the bridge humbucker to it's inside coil
Split the neck humbucker to it's outside coil
Switch the phase of one of the pickups (in relation to the other pickup - not in relation to its own coils) when the pickups are not split.

I hope I've got that clear enough. Frankly I keep confusing myself with it.

Is this even possible with a single push-pull pot? I've seen on the SD website a diagram for doing split and phase with two push-pulls, but I'm thinking that's when both pickups are being split to the inside coil, or both split to the outside coil. If one was split to the inside coil and one was being split to the outside coil, wouldn't that normally knock the pickups out of phase? So if they're wired out of phase already, would this then wire them back in phase when split?

... Okay, my head hurts. This board hasn't let me down in the past, hopefully one of y'all is able to decipher what I mean.

A DPDT push pull pot does not have enough contacts to perform all three of the functions that you listed.

EDIT: I feel compelled to ask one question. Is this circuitry proposal of yours based on having heard the above-mentioned coil combinations or just on what you hope they would sound like?

SUGGESTION: Spend an hour or so trying out the various coil and phase relationship permuatations on your list. For the purposes of experimentation, twisting the conductor wire ends together would suffice. Keep notes of which combinations sound good and which do not.

Ok, I read the post a couple times and it looks like this is what's being requested:

Down: Peter Green mod, ie. one humbucker out of phase with the other.
Up: Both pickups split to neck-facing coils, in phase with each other.

It actually sounds like a pretty sweet arrangement to me. I'll have stew on it a bit but my inclination is there simply aren't enough poles to do this.

Yeah, that's exactly what it is. I feel quite ashamed for not being able to explain it that clearly myself.

These are sounds I have on other guitars currently. All of my guitars with humbuckers are wired with one pickup out of phase with the other, it's a tone I use all the time. I have several others with splits; I've found I prefer the neck-facing coils split and I've tried out of phase singles before, didn't like it. One of my guitars does actually have these options already but it uses three controls to do it (two splits and a phase), which I find far too much of a hassle to use while playing, especially since the pickup toggle switch is of course on the opppsite end of the guitar's body to the rest of the controls. So I'm trying to get something together that'll get me the same tones but with a much simplified control scheme.

But it sounds how I feared, that one pot simply doesn't have the capacity to do it all in one.

Common guys - lots of new people out there, let's bring the A game for advice!
