The Chance Vought V-173 "flying pancake""flying pancake" was designed to provide low speed flight with very low aspect ratio wings. In fact, the entire body is a wing and the twin propellers are arranged to blow their slip stream over that body. It could very nearly hover, so the lift coefficient is extremely high.
With modern flight control computers the vestigial horizontal tail could be incorporated into the rear fuselage as is done with flying wings. You can see that this has already been done with the center part of the tail. If you were concerned about the width of the props, they could be moved inboard and wing twist altered.
