I'm wondering if this would make a difference or not if it was filled/stuffed in the open areas underneath.

I think it would. Pretty sure someone stuffed a moving blanket in there and noticed a difference. And quietest my car has ever been was when I had a couple good size soft-sided coolers in the back. IMHO, the big thing is to keep the sound from bouncing off the glass and forward to the seats. The glass is like a perfect cone to send the sound forward. Not sure that it's as much of a decibel problem as it is a focus of the soundwaves problem.
