I would use all baths at >20C.

In order to post-swell the emulsion you might try also a 5% glycerol (sorbitol would be another option) solution.

I assume this would imply to develop (or re-develop) the emulsion to increased densities. Then you'd have to use a rehalogenating bleach that does very little damage to the integrity of the Lippmann fringes. Bleaches based on ferric EDTA or copper sulfate, maybe on iodine would come to my mind. The "classic" method implies mercuric chloride but that one surely has to be ruled out.
