You can use a host pts device for this. Have one UML hook itself up to the master side (conx=pts) and have the the other hook itself up to the slave side (I think it's a tty, so conx=tty:/dev/pts/n once you've asked the first UML what pts device it got). Host devices aren't opened until something inside the UML opens the UML /dev/ttyx, so there will have to be a getty or something running on it before you ask about what host pts device it got.
