building a thermal mass with soil

Hello friends!
We are in the permitting process for our new home and it originally had two Ground Source Heat Pumps, one for hydronics and the other for HVAC for the brief air conditioning season.
Now I am exploring the idea of collecting heat in vacuum tube collectors and storing it in an insulated mass for a seasonal storage system.
I have a contact for free insulation from a manufacturing process, which changes the economics considerably. I can get an R value of R80 around the mass.
I see that traffic is way down here. I will wait and see if there is any interest from the old guard for discussing it further.
