Well, I got the idea of creating a finished Attic in my house. But , the Furnace ductwork is in the attic. Could I install plastic sheeting in the roof rafters and then put the pink fiberglass insulation between the rafters then nail up some drywall ? After that, blow some more loose cellulose insulation in the floor of the attic and then build up the floor of the Attic , to later install plywood for a floor ?

If you insulate the rafters be sure to leave an air gap so the underside of the roof can breathe to prevent ice dams and mold problem. You'll also need good soffet ventilation and a ridge vent.
