Huh?  The Presentation Manager allows arbitrary output to be
associated with an object, e.g.

(defun number-circle (number x y &optional (stream *standard-output*))
  (dw:with-output-as-presentation (:object number :type 'number
				   :stream stream)
    (graphics:draw-circle x y number :stream stream)))

This displays a circle but it is treated as a number.  While it isn't
currently possible to make the default output format of a presentation
type be graphical, the above mechanism provides most of the
flexibility you need.
