You could also consider a DDMTD as useed in CERN's White rabbit project.Apart
from the sine to logic level conversion its all digital. With care in the
design the jitter should be sub picosecond.

My little HP5065 project is continually running into the jitter of
my HP5370B counter which is annoying me, so I'm looking int DMTD.
Everybody seems to be using traditional diode-mixers for DMTD,
and to be honest I fail to see the attraction.
Why wouldn't a analog multiplier like AD835 be better idea ?
What am I overlooking ?

Never attribute to malice what can adequately be explained by incompetence.
