"sweep" and "crystal controlled" seem to me to be mutually exclusive.
I once made a sweep generator for a specific job that used crystals
to generate frequency markers,(displayed on a scope). What
output/human interface are you
expecting?

I've substituted a ceramic resonator for the usual crystal to get more
'pull' over it. At the moment it's working well and I'm getting stable
output from 3.46Mhz-3.58Mhz which I'm very pleased with. Next problem
is to oust the variable trimmer cap and replace with suitable
varactor(s) for better frequency control...
