THX, Rick! Doing a couple of mods will make it far more flexible.
Re-assign pins 5-11 to USB/whatever from the serial port I needed back in the day and it will work on USB Macs as well.
Substitute VGA for the LC Video in the spec and use VGA Converters for the vintage Macs will make it more flexible still.
The DB-25 cabling can then serve a mixture of ADB Macs, USB Macs and PCs.
You'd still need the Equivalent of the MiniView Macintosh Converter in the first diagram I posted, but like in that diagram, it can be a separate box.
I did some skulking around on eBay and it looks like PS/2 switchboxen may be a more elegant solution. Say: three PCs and Macs on a four-way USB switchbox and hook the fourthe cable set to the input side of a four-way PS/2 switchbox, for three more CPUs with a downlink to another PS/2 switchbox.
Run your USB over the mouse circuit and ADB over the KBD circuit, doing either connector adaptation at each CPU. The USB->ADB coverter box would be inserted wherever needed on the PS/2 KVM tree.
I'm tired, so this is kinda blurry for me as well.
