I don't know how likely it is to be working anyways. Have you considered using an OCXO for simplicity reasons? There are reasonably priced boards on eBay that have an OCXO and just the necessary components around to run it, like [2,3]. Those should be sufficient regarding accuracy, though output waveform is sine, which is acceptable but not ideal. I have just invested 2 minutes in research. I am sure even better suitable options can be found easily.
