I've come up with a possible solution, so I thought I may as well document it here as an answer.

A process can pass a socket over to another process via a call to WSADuplicateSocket, so a coordinating process could bind to a dynamic port, and internally associate it with a given IPC name. When a ZMQ server process wanting to "bind" to that name arrives, the coordinating process copies the bound socket to the server process and closes its own copy.

This solution doesn't address my preference to avoid calling bind(), but that may not be strictly necessary; I'll have to perform some tests.
