How to build thermal mass around Fisher Wood Stove?

We have a Mamma Bear Fisher Wood Stove in our basement. The basement is small (about 20 feet by 16), regular cement block walls and concrete floor. Upstairs in the living room are two floor vents that open so the heat from basement comes up. Also, vents are in steps which points the warm air up into the loft.

I want to add some type of thermal mass around the Fisher to see if that will help hold and then release heat? Anyone ever do something like this? Someone recently gave me 200 cement blocks and so I started thinking about this. I would not try to cement or cover up the wood stove - that does not seem safe. But, would it help to just dry stack cement blocks around the sides and back of the stove?

Or is that just causing work with little results?

The Fisher works pretty good. Takes a long time to get going but once it is going, we can almost heat the house with it. It does die back mostly at night. We put a green stick on it at bedtime and damper down.

Any point in trying to add thermal mass around it? Thank you.
