Several issues here:
1. Making a precision crystal like the 10811 one is very involved.
It cannot simply be rescaled to a different frequency. It represents
a whole new design. This is not like ordering custom crystals for
your 2 way radio (back in the day).
2. The 10.23 MHz crystals I am
I have a 10.23 MHz 10811 oscillator out of an early GPS simulator
somewhere, so, FWIW, HP did make at least one. I remember it because I was
disappointed it was not 10.000 or 10.24 MHz.

Several issues here:

Having seen the note on alternate crystals for the HP10811 oscillator I was
wondering if its realistically possible to re-crystal one to frequencies in
the 20 MHz range? Some other components may need to be changed of course but
is this worthwhile exploring? Who would be a good vendor for a few
Demian,
the big question is, what are your requirements?
Long term stability, phase noise, ADEV,...?
You'll probably spend a multiple of what a finished product costs to get
the 10811A with a cstom made x-tal on specs. Not to speak of the phase
noise test equipment needed, that will break
