Well, one possible remedy would be to place the fmffile stuff _around_
\begin{document}...\end{document}.  Then it should be active on each
run.  No idea whether this will do more harm than good though, and
you'd quite probably need to use METAPOST on every run if you hope to
achieve anything close to consistency (not sure how the "counters"
option might interact here.  If you use that, you probably should
_not_ run METAPOST when regenerating regions).

There are also regular expressions to tell AUCTeX what to include in
every region compilation, and those expressions usually take
everything outside of \begin{document} and \end{document}.

Those are in TeX-header-end and TeX-trailer-start.  You could adjust
them to include the file writing code from feynmp.

Well, choose a keyboard binding and write a toggle for it.  About 5
lines of Lisp code, something like

(defun TeX-toggle-escape nil (interactive)
  (if (string= LaTeX-command "latex") "latex -shell-escape" "latex"))

(add-hook 'LaTeX-mode-hook
  (lambda nil
    (define-key LaTeX-mode-map "\C-c\C-t\C-x" 'TeX-toggle-escape)))
