It will be easier to use a src block for a faux language (say FOO).

Customize `org-babel-execute:FOO' as needed and you should be set:

#+BEGIN_SRC emacs-lisp
   (defun org-babel-execute:FOO (body params &optional etc)
     (concat  body (format " %S" (assoc :bar params))))
#+END_SRC

#+RESULTS:
: org-babel-execute:FOO

#+NAME: example1
#+BEGIN_SRC FOO :bar baz qux :exports results
whatever
#+END_SRC

#+RESULTS: example1
: whatever (:bar . "baz qux")

HTH,
