I can (and plan to) take on that task once a design is agreed upon.  I
don't really know much about Org internals, but I think I can figure
out.

I do like that syntax.  A minor addition might be for the case when one
wants to pass the value of a variable local to the org buffer to the
editing buffer:

-*- fill-column: 65; indent-tabs-mode: nil -*-
#+edit-vars: (indent-tabs-mode)
#+begin_src emacs-lisp :edit-vars (fill-column (lexical-binding t))
;; here, when editing, fill-column is 65, lexical binding is t
;; and indent-tabs-mode is nil
#+end_src

Whoops! Sorry, yeah, I have been hitting the wrong keybinding for the
last couple of messages I think...
