I ended up picking up some oscillators for this job.
1) It's only a couple-off project, so no big cost constraint.
2) Bound to be more reliable, and easier to get working right.
3) The greater precision is an advantage here.
4) I realized I could use the OSC_OUT (At CLK/4) as a deglitch
   clock for a BiPhase-L output that got added at the last minute!

Thanks for all the suggestions!
