I belive DC-10s are already stage-III compliant, I know the L-1011 is.
For that matter, I think the 747-100 is. Your comment does apply to the
DC-9 fleet, but since a number of cargo carriers have found it quite
economical to hushkit DC-9s and 727s, I don't see why it would be any
less feasible for a passenger carrier. I had heard once or twice that
Delta may hushkit quite a few 727s, but I've never had that confirmed
