  I have done the same to use C-h for backward-delete

  I've done considerable keybinding in the past, using emacs in gui
  mode on linux. So I've done considerable rewriting for OS X and
  terminal environment what follows is untested but should give an
  idea :

;; Could be a "template" for other rebindings
(defun tj-control-j ()
  "Function to call when control-j is rebound"
    ((string-equal mode-name "Lisp Interaction")
;; set up the keymap
; Movement related bindings
(global-unset-key "\C-j")
(defvar tj-go-map (make-sparse-keymap) "Control-j")
(define-prefix-command 'tj-go-map)
(global-set-key "\C-j" 'tj-go-map)
;; rebind the original C-j
(define-key tj-go-map (kbd "j") 'tj-control-j)

No doubt there is going to be some glitches, but the next
few days will finish the story ...
