I  don't have a tried-and-true technique.  After I made the best  copy and prints I  would  I'd try to flatten the acetate.   If it  was mine I'd  put the  negative at 40-50%RH @ 68F  between two pieces of glass. Then store it  at a warm temperature to not exceed 100F. (light bulb).   I would let it sit for a month with a book  on the glass.  This may allow the acetate to relax.

While I lack anything remotely approaching Bob's experience, this is pretty-much
the technique I figured would work.
I'd open the sandwich  once week  to let the film acclimate to pickup some 
humidity.

Exactly, though perhaps a 50% RH 'soak' for a few days before sandwiching
it would be enough - I sort-of thing the emulsion won't dry-out rapidly in
the sandwich if stored at ~50% RH (where would the water go?)
