It's not the push-pin/patch cord kinda thingy you described, but how
about simply using a component carrier and solder jumper wires to make
the pin-pin cross connections. You would wire as many carrier jumper
boards as you have cable combinations.
example component carrier - https://www.peconnectors.com/component-carriers/
Then simply drop one of the jumper boards into a ZIF socket that you've
soldered the wires from each cable to each row of pins. The ZIF socket
pin -> wire connection would work best on a small perf board with
holes/solder pads for a sturdier connection.

The ZIF socket would probably need to be soldered to a perf board to
actually make those solder connections sturdy.

I want to make a rewirable adaptor (OBDII to DB15)
One neat way to do this would be with a matrix, where you plug something
into holes and that connects the row to the column.
As a CNC link (almost) I think that something like this was used on the MEC
Microsprint programmable lathes where things often called "diodes" were
plugged into holes to program the machine.
I feel that a couple of PCBs. spaced a small distance apart, could have
plated-through holes linked by "something" being plugged through them. The
problem being to find the "something" that will make contact with two holes
at the same time.
A single PCB and an array of jumpers would work, but that would be 480 pins
to keep track of
The plated-hole idea has 240 holes, but only needs 8 plugs to do the
programming I need.
2mm banana plugs do exist.

But I am not sure if they will reliably connect two plated holes.
