All of the foil insulation products need airspace to do their thing. Sandwiching it between pine and plywood will not give you the desired effects.
How about
-heavier pine ceiling
-1" or 1.5" of Polyiso insulation with routered out pex channels
-printing plate transfer plates
-heavier finished floor
