There are industrial foams that will expand and harden in a closed space.  I
used to work at a hot-tub manufacturing company.  We used isocynate foam to
coat the underneath of the tubs to insulate them.  It was a two-part mixture
that was blended as it was sprayed.  It expanded and hardened in seconds.
Too fast for this purpose, but there might be other two-part foams available
that have a slower reaction rate. Might try some industrial chemical
suppliers.  Watch what you're getting though.  The foam we used was highly
poisonous and we had to wear a breathing apparatus just to be in the same
room.
