True, unless the joists count as mechanical ground. But the floor boards themselves are included in the model, as C1. I did leave that out.

Regardless, the diagram reminds me of a VPI turntable base I had years ago with a sandwich of steel plates (with heavy fibreboard glued in between) that was suspended on springs, and the turntable sat on top of that. I don't know if it helped or didn't - I imagine the effect (if any) was subtle. So much would come down to the tuning of that bandpass filter, and there are a lot of variables to manipulate (including the floorboards :-)
