Impossible furnace room ceiling?

Hey there, my basement is finished except for the furnace room - the ducts and piping create what looks like an impossible drywall job (see the pictures). My reason for covering it is to reduce sound transmission to upstairs, as well as the adjacent rooms in the basement. It's not just the furnace noise that travels upstairs, but any noise from the surround areas in the basement comes through upstairs in the area above the exposed ceiling. The only thing I think of is to use fire retardant roxul batting between the joists and then wrap some layer under the batting to prevent fibres from spreading into the air. Manipulating the wrap under/around the ducting would be difficult but not impossible like drywalling looks to be. Is this doable, are there any better solutions. Looking for some answers.
