Interesting. That’s a low part count for a 4 way crossover. But you can see the red and black input wires, then the 4 pairs of outputs.

You, or someone, should trace it out and make a wiring diagram. From a first look you might need a separate PCB for the new half.
But tracing it out will tell you.

It's a very old but still capable speaker. Transmission line design, the sound is very good, I have them connected via a trio ka4004 pre into a Sony ta1144 power. What sound!! Having the amps this way set up sounds alive, the way bass drums and other lows are played truely slam hard. Higher frequencies need help with separating so I thought I'd try to bi amp..see what happens
 
Ok, it seems the previous circuit checks out.

Splitting off the woofer would be easy. The others are linked by the cascading filters. You'd have to develop a replacement. I could see that happening in a couple of ways. You might try finding the response at the junction of the three upper drivers at the output of the first high pass filter, and use this as pre EQ to the 3 upper amps while keeping the remaining components in place.. or you could find the responses at each driver and replicate that using your own filter for each.
