The following functions provide for (1) easily executing code in the
org-mode buffer related to the current edit buffer and (2) tangling the
org-mode buffer related to the current edit buffer.  Binding (2) to a
key in `org-src-mode' should provide the functionality you describe.

#+BEGIN_SRC emacs-lisp
  (defmacro org-src-in-org-buffer (&rest body)
    `(save-window-excursion
       (org-edit-src-exit 'save)
       ,@body
       (setq msg (current-message))
       (if (eq org-src-window-setup 'other-frame)
           (let ((org-src-window-setup 'current-window))
             (org-edit-src-code 'save))
         (org-edit-src-code 'save))
       (message (or msg ""))))

  (defun org-src-tangle (arg)
    (interactive "P")
    (org-src-in-org-buffer (org-babel-tangle arg)))
#+END_SRC

I think that the above should be folded into org-src.el, but I'm not
entirely sure how.  (1) could be used to perform a number of functions
in the org buffer from an edit buffer, although off the top of my head
I'm not sure if there exists a need for this aside from tangling.

Best,
