binding to "cp" without breaking "c"

Not sure how ugly it would end up, indeed.

But you could very well handle it with something like:

   (define-key map "c" operator-arg-map)
   (defvar operator-arg-map
     (let ((map (make-sparse-keymap)))
       (dotimes (i 10)
         (define-key map (vector (+ i ?0)) map))
       (define-key map [?w] 'my-command)
       map))

   (defun my-command (keys)
     (interactive (list (this-single-command-keys)))
     ... analyze keys to extract the count and the motion...
     ...)

It would probably introduce other changes to the behavior that you
didn't intend, and such "recursive maps" are sufficiently rare that you
might bump into Emacs bugs, so yes... not necessarily a good idea.

OK, going back to lurk mode before I start rambling about set-transient-map.
