I am not sure it addresses your question (in particular, I do not redefine
C-c), and I have read that this way is frowned upon, but here is what I do:

;; First:
(defvar my-keys-minor-mode-map (make-keymap) "my-keys-minor-mode keymap.")

;; Then all my keys like that:
(define-key my-keys-minor-mode-map "\M-." 'scroll-up)
