This is what I got in my init.el now (improved version with global
keybindings). And I like, will probably become one of those commands I
use all the time. 

I already used it to wrap the following code in 3 src-blocks:

#+begin_src emacs-lisp
(defun tj/wrap-sexp-or-reg-in-src-block (&optional lang lines)
  "Wrap sexp at point or region (point +-lines) in src block"
  (interactive
   (when current-prefix-arg
     (list
      (ido-completing-read "Org-Babel language: "
                           (mapcar
                            (lambda (--lang)
                              (symbol-name (car --lang)))
                            org-babel-load-languages)
                           nil nil nil nil "emacs-lisp")
      (read-number "Number of lines to wrap: " 1))))
  (let* ((language (or lang "emacs-lisp"))
         (marker (point-marker))
         (beg (point))
         (bol (bolp))
         (end (if lines
                  (save-excursion
                    (forward-line lines) (point))
                (save-excursion
                  (forward-sexp) (point))))
         (cut-strg (buffer-substring beg end)))
    (delete-region beg end)
    (goto-char (marker-position marker))
    (insert
     (format
      "%s#+begin_src %s\n%s%s#+end_src\n"
      (if bol "" "\n")
      language
      cut-strg
      (if lines "" "\n")))
    (set-marker marker nil)))
#+end_src

#+begin_src emacs-lisp
(global-set-key (kbd "C-c w l")
                (lambda ()
                  (interactive)
                  (let ((current-prefix-arg '(4)))
                     (call-interactively
                      'tj/wrap-sexp-or-reg-in-src-block))))
#+end_src


#+begin_src emacs-lisp
(global-set-key (kbd "C-c w w")
                'tj/wrap-sexp-or-reg-in-src-block)
#+end_src
