Is it something you can define an inherited property or a tag for, and
then add some advice around org-babel-execute:python to check that
property and use let to bind org-babel-python-comand?

Maybe something like this, for example:

#+begin_src emacs-lisp
(defadvice org-babel-execute:python (around will activate)
  (if (member "python2" (org-get-tags-at))
    (let ((org-babel-python-command "/path/to/python2"))
      ad-do-it)
    ad-do-it))
#+end_src
	
* Test :python2:
#+begin_src python
return 1 + 3
#+end_src
