I have always wondered what a version of the Enterprise would look like with 'pylons' that look more like 'wings'....attached along the full length of the nacelles and on a corresponding length of the hull. A hull that is longer and the back end of which ends even with the back end of the nacelles. And a neck that is medium height, but much more substantial and supportive around more of the perimeter of the back half of the saucer. But....I am not an artist.
