Why do you need paver stones to put the smoker on? That is what the lid of the next hive over is for ;) I use the cinderblocks also, but if I really had the setup I wanted, I would have benches for my hives. I would set four posts in concrete, brace them diagonally, and then frame the top of the posts with 2x6 pressure treated wood. Each bench would take 5 or 6 hives with 8-10 inches of space between hives. In the winter, I could push all the hives snugly together, and then wrap the whole block.
