Morgan Devalis, I know, has used a lot of CAV minis as Mechs. He's also done a lot of custom tinkering, sometimes mixing and matching CAV stuff on to BattleMech figs, and vice-versa.
As for me, I only have one CAV mini, but I use it as an 85-ton Mech. I'd have to ask Morgan what the CAV name of it was, but here's the way he designed it ('twas a b-day present):
