I use the following to write Emacs Lisp in my usenet postings:

(defun egoge-write-elisp ()
  (interactive)
  (if (not (eq major-mode 'message-mode))
      (message "Not a message buffer.")
    (switch-to-buffer (make-indirect-buffer (current-buffer)
                                            "*emacs-lisp-message*"))
    (emacs-lisp-mode)))


I guess, this could serve as a starter for you.

However, I do believe that mmm-mode would provide a more elegant
solution. I never really used it, but the last time I checked I was
not forced at all to use some tags, but IIRC I just issued a command
on a region and then for text in that region Emacs behaved as if a
different major mode were active, an effect that was lost once I
revisited the file.
