FWIW, the original palm pistols used a .32 Extra Short rimfire cartridge, made necessary by the design, which was loaded from the inside of the flat "cylinder". With a case length less than half that of the .32 S&W Long, it was not exactly the .454 of its day. But it fired seven rounds, not one.
See the excellent pictures at the link shown in #14. Mine is not quite as nice but is fully functional and only cost $700, a third of what they are asking.
My idea would be a more or less conventional revolver with a bracket extending forward from the butt and around to the frame below the barrel. A lever would be attached to that and to the trigger so that squeezing the lever with four fingers would pull the trigger in a DAO manner.
