Whew, I feel for you.
Is the duct work completely sealed? Can you get to the ducts from some other part of the house? The only think I can think of would be to create some sort of isolated/baffle system.
This only works if you have about 4' x 1' x 2' of space. Basically you need to cut out a section of the solid duct work and insert a long piece of the flexible stuff with several bends in it. This would help a little, but to really make it right it should be a seperate run from the air handler. I assume the sound transmission is through a "shared run" that is in another room?
Ack... Good luck..
