Yes, we have designed the poly hive so that you can use wooden hive parts with them.  Whether that is using a wooden brood box on the poly floor or wooden supers on your poly brood box.   The only limitation is that a wooden roof won't fit over a poly brood box or poly super.   This is because although the internal dimensions are the same, the poly has thicker walls and so a bigger external dimension (footprint).    You can get around this by either always using a wooden super as your top super, or just use a poly roof.
