One additional point on the negative side. A big reason you will not see over
wing engines on low wing transports is noise. The noise created by the hot
section efflux shear, and the high pitch of the N1 fan would be much louder
in the passenger cabin. More weight in sound insulation or marginally
effective active sound reduction would be necessary, and still would not
bring levels to what we expect in a modern airliner.
