Well,  Owen,  we'll see.
Perhaps some day.
 It's an old house. Both floors have 10 ft ceilings, there's a "staircase".. the hallway, from bottom to top is 20 ft. The 1st floor has the entranceway (stairs), formal living room, library, family room, 20'X 25' kitchen, dining room, full bathroom, and 3 - season room.
 The 2nd floor has a full bathroom, 4 bedrooms, one is the cats' apt, 20X25'.  It is the future Hoover gallery. It was suggested that the "pipes" could go through closets; 2 inlets on each floor.There are 4 cellars, so under access is easy.
 Regardless,  I love the quadraflex nozzles.
 Tom A. stressed the inlets have the "logo" on them, of course.
  At this time,  I can find more practical things on which to spend that money.
  But, I SO appreciate your input.
  We'll see..........................
