Something like this?

(defcustom keymap-additions nil
"Alist of bindings to add to keymaps at startup.
Keys are keymap symbols, values are lists of conses, format
(key-binding . command)

Where KEY-BINDING is a kbd format key specification, and COMMAND is an
Emacs command.")

So you could have that be

'((fundamental-mode-map . (("C-a" . mark-whole-buffer)
                           ("C-b" . backward-word)))
  (elisp-mode-map . (("C-a" . mark-defun))))
