In looking at the CRD idea, it is not obvious to me how either
of the 16M0 Hz or the 10M0 Hz signal would contain any
relevant energy that would give the precision necessary for
the desired ideal result.
The only harmonic relationship that I can see is to square up
the clean analog and divide by 13 down to 2M0 Hz, thence use
the 5th and 8th harmonics at 10M0 and 16M0 but then why
use the 16M0 at all?
I expect that I am missing something obvious here
a little nudge may help.

Never having used one of those, I'm thinking I'd need two mixers, a
10MHz bandpass filter and a 16 MHz bandpass filter. I'm guessing
there would need to be some gain in the system too.
How stable are these? Seems to me If the bandpass filters were
temperature sensitive the 10MHz output would drift around. What
types of filters and mixers are typically used?
I wonder if "conjugate regenerative divider" qualifies as an
inexpensive converter
