Well a coax just carries a digital signal, so i believe that you just get two cables, so indeed its just like a rca but the cable is usually shielded.
So assuming that one have 2 coax inputs that are not active at the same time and only one coax input one may try to use the following elementary solution :

That one if more a splitter, so imagine it with male replacing female and vice-versa (or add 2 male -> female and one female -> male adaptors).
One could as well cut the coax connector merge the 4 wires two by two and insert them into a coax connector.
It should work as long as only one input is active, but if by mistake both are active this could lead to troubles since the amperage at the DAC input will then be twice what it should be , and even when one unit is active and the other plugged but inactive we shall get a potential difference at the output of the inactive unit, i wonder if this could damage it.
Someone post a merger/switch but it cost like 150 dollars if you add the coax option and it is overkill since you get then a switch operating 4 spif and 3 coax with 1 optical out and 1 coax out.
So any cheap and elementary slution is welcome.
