Concur with the comments on QE2's classic funnel! When developed, the funnel was a departure from all convention to date - truly an original innovation.
With heights of cruise ships being constrained by the bridges they need to pass under and technology allowing for more real estate in the superstructure (remember QE2 added a deck with her "new" aluminum superstructure), funnel heights need to remain constant as the superstructure creeps higher making a squattier funnel which I think horribly detracts from the look of the ship if it is using a QE2 influenced design.
Also adding a QE2 funnel to a classic liner doesn't work as QE2's lines are forward leaning (wheel house, mast, funnel and her aft cascading decks to some extent) where her predecessors, including Normandie, leaned aft.
QE2 is one of a kind and they truly broke the mold after they made her!
