This is what I successfully used for many years to dedicate the whole
C-z kemap to user-defined keys while keeping suspend-frame on C-z C-z:

#+begin_src emacs-lisp
(defvar my-map
  (let ((map (make-sparse-keymap))
        (old (global-key-binding "\C-z")))
    (global-unset-key "\C-z")
    (define-key global-map "\C-z" map)
    (define-key map "\C-z" old)
    map))
#+end_src

And when cua-mode is enabled, C-z is bound to undo.
