Well, you could try it out and see!  Facing a similar clocking issue on a
6bit->8bit converter project a long time ago, I punted, put in a 555
oscillator with a pot, and then adjusted the pot to the middle of the range
where I was seeing reasonable characters at the output (as read by the other
computer) and no framing errors on the input.  The range was pretty broad,
and this was for a temp-controlled environment so I wasn't very worried
about drift.  It worked for quite a long time...
