It would be much easier to modify the A-182 by adding a diode between each socket and switch. Simply interrupt the pcb track between socket and switch, solder a diode between socket and switch (the schematics is shown on the
A-186 page) and add an output socket. That way you obtain a "switched" A-186 gate/trigger combiner.

It would probably take only a few hours to "condense" the A-182 pcb and front panel to obtain such a module (with 9 sockets and 8 switches). But I'm not sure if there are sufficient inquiries for such a module. An additional option would be select between "DC coupled combination" (i.e. gate remains a steady gate signal at the sum) or "AC coupled combination" (i.e. only the rising edges of the inputs signals are used to generate the combined trigger signal). The two types could be distinguished by left/right positions of the switches (center = off).

Best wishes
