It sounds like you don't want to "re-engineer" the whole thing; you
just want to appropriate the prefix argument for your own purposes.
Exactly like `find-file-at-point' does to `ffap-file-finder'. ;-)

So, along those lines, something like:

(defun my-ffap (&optional filename)
  (interactive)
  (let ((ffap-url-fetcher (if current-prefix-arg
                              #'browse-url-firefox
                            ffap-url-fetcher))
        (current-prefix-arg nil))
    (find-file-at-point filename)))

should do the trick.
