I was wondering if you remove the sound deadening (proofing) from the vehicle.
Would you compensate the majority of the loss of sound proof by installing a belly pan (Full).?

You could save potential 40 lbs and still have more or less noise in cabin?

Maybe a very thin layer of a sound proof material (light weight of course) stuck on the belly pan. At the same time this material could be heat resistant.

? acoustic foam thin , lightweight. Not sure if they are fire proof.

Solve two problems at once maybe.
