Would the Messerschmitt Bf 110 have made a good torpedo bomber?
Short answerIt might have worked after considerable development, but Germany pursued the Stuka more seriously for torpedo attack.
NotesThe Bf 110 had enough potential to become a torpedo bomber after substantial development. The existing fighter airframe was not ready to assume the mission without modification and testing. German work appears to have concentrated on fighter-bomber uses for the Bf 110 rather than a torpedo version. The Stuka received more serious attention for torpedo attack, making it the more mature German route into the role.
