This is not exactly what you're looking for, but take a look at the
mode-local package which now ships with Emacs. It's in the lisp/cedet
directory and lets you define variables and functions dependent on the
major-mode.

In a nutshell:

(define-overloadable-function somefunc (params)
 "doc-string")

(defun somefunc-default (params)
 "doc-string"
 ... default behavior ...)

(define-mode-local-override somefunc org-mode (params)
 "doc-string"
 ... behavior for org-mode ...)
