Using comegen(termite) nest as a substrate for fructification?

Hi people, im in The Amazon jungle. I been doing a Lot of experiments for spreading Spawn.
Now i want to start producing mushrroms.

I made my first fruiting bag using sawdust, but it occurred to me to use termite( comegen)  mound material as a substrate instead of sawdust? What do you think?

In nature, when I put a piece of termite mound on mycelium, the mycelium colonizes the mound.
