Once I realized that in practice my better OCXO's were typically more than stable enough for my intended uses things became much simpler.   I also realized that I could utilize my collection of time interval counters to compare my chosen reference to other references (including a GPSDO) while also comparing the chosen reference to the "Device Under Test."  I realize this isn't likely an approach that a commercial lab would use but for my hobby use it seems to work ok for me.

You already have a home brew GPSDO.. YOU are the control loop and the 
screwdriver is the actuator.<grin>
