If I were to fill the interiors and cover them with fabric I think they could function for absorption. Something I have on hand is plenty of styrofoam peanuts and plastic netting that people use in their gardens. It wouldn't cost me anything to experiment so I think I'll give it a go. Do you guys think the styrofoam peanuts are a bad idea? Thinking all of the air pockets between them might create an absorbing condition. All advice appreciated

I'll bet they'd do
something to the sound. Whether you'd like it or not, that's another question. Since it's free, if you don't mind the time I'd try it and find out if you hear anything interesting, good or bad. I doubt there will be much, if any bass absorption. But there may be a mixture of high frequency absorption and scattering. I did an experiment years ago, hanging strips made of office paper sheets - about 5 sheets thick - all over my ceiling. That had a very nice effect on my room's sound, but besides looking odd I deemed it a fire hazard.
