Yes, I've mentioned the possibility of using two back to back 4051s a few times - the main thing I don't like about that is the lack of isolation - I wanted to be able to upload demo software into the MK14 and then unplug the interface to leave the MK14 running stand-alone. Otherwise the use of a pair of 4051s is a great way to do it and requires very few lines of I/O (...7) from the controlling micro.
