Ya know George I like the way your brain works in the morning. I pictured in my head the puffy fiberglass like stuff and what a mess it would be then I remembered they use the pink board stuff at work to line boxes with, a stack/ block of those cut to fit and covered with plastic wrap should do the trick.

How about one simply cut to fit one of the shelves dividing the Cambro ? That way the potential metal from using a pan to hold the insulation wouldn't 'eat up' the heat.
