pyzmq offers something called select, which works just like select except it works on both file descriptors and ZeroMQ Sockets. It just delegates all of the work to libzmq. We could use ThreadedSelectReactor and have it use ZMQ's select. I'm not sure if it should use "normal" select everywhere else: because zmq's select is in fact much better than select.select (it just behaves like select.select in the sense that you give it three sets of fds and an optional timeout; under the hood it's actually epoll or kqueue or whatever) and it can handle plain old file descriptors just fine. So, you'd have a TRS with either 1 zmq.select running on everything or 1 zmq.select running over Sockets and 1 select.select running over your classic fds. Personally I kind of like the idea of zmq's select taking over, but I don't know how well that works in practice.
You should probably just make a ZeroMQ reactor, instead of using TSR, which (in its current form) is an ugly hack. TSR buys you nothing because, unfortunately, it doesn't let you hook up to arbitrary reactors. If the API really is select() compatible this presumably would be a fairly trivial subclass of the reactor in twisted.internet.selectreactor.
