Yes, it's been done. Depending on the version you have, and what chain rings you're using, the chain may sag on the small-small combo if you have the short or medium cage version (Vx or Vx-S/T). The long cage Vx-GT will handle pretty much anything.
Used to use a sun tour VX-GT long cage rear Mech on a 14-34 rear & 68T front chainring when I was attending college back in the early 80’s never had any issues although I wasn’t running any inner ring at the time......
