OK, so what I'm seeing with the Hofner diagram, 3 pickups, each has its own tone pot,although the bridge pickup's set-up is different. With all 3 pickups, it seems that the variation in cap and resistor values is meant to use 3 identical coils to mimic a matched Strat set
Each pickup then has its own on-off switch.which connect to a master Vol, and then to a slide switch which selects another pot and cap arrangement, or bypasses the extra pot.
Bunny, you seem to be the guru of cutting resistance tracks to make no-load pots. At times here, every pickup will have 3 pots in circuit. So you might want to have one or more of those pots be no-loads with cut tracks, so as to avoid having 3 pots dulling the signal at times.
As would I,I'm not clear on what all those caps and resistors are supposed to be achieving in this scheme. But as far as different? Not sure I follow you, there are any number of things that can be done passively which are "different", but as Ecclesiastes notes, "there is no new thing under the Sun".
5 or 6 coils, SC or HB, are the practical maximums, and there are only so many ways to connect those coils.
The Les Paul Studio gave way to the Les Paul Recording, which used low-impedance pickups and similar wiring to the Studio model. Not sure what the Hofner model is, I'd have to google it.

As with so many Designs online .. there are a lot of different ones out there .. going off at different angles  To me the TOP Circuit, looks like Neck/Middle have a Very small Bass Control and Treble Control i did read once that the 250K Resister next to the 1M was a TrimPot  Site |

 Im looking at this Photo, the 3 Switch system ive seen but on a 2 Pickup system! The Rhythm/Solo is on this circuit what puzzles me is 2 Volumes and 2 Tone Pots and i dont konw what that BLACK thing is about Rhythm and under the Jack socket vintage-wiring-schematics trying to focus on their guitar designs (mainly the last and over done ones to reduce it to what i want) They also did a FAMOUS line of Bass the Voilin Bass (as the Beatles used) |

I’m thinking the top two pickups have some sort of variable mid scoop and the bridge is just a shelving high pass filter. The whole mix is then high passed, and the network on the switch adjusts the cutoff of that, but it just kind of eyeballing it doesn’t really seem it cando much either way.
