Just get yourself an extra multiplexor and connect null modem cables between every pair. Run a getty (or even a shell!) on the odd ones and nothing on the even ones. Rename the even ones /dev/pty[0-3] and the odd ones /dev/ttyp[0-3] (I am assuming an 8 channel mux). OK, OK, so I'd really have `real' pseudo-ttys than `pseudo' real-ttys, but if that's what you're stuck with it just might work.
