It depends what you want. Tangling actually is for removing the Org
text from Org-mode files, just leaving the content of source blocks,
so your whole idea is a bit against the flow.
If you want to conserve the whole node you probably need to wrap it
in #+BEGIN_SRC org ... #+END_SRC.
If you want to transform it to a source block you could use org-dp.el:
#+BEGIN_SRC elisp
(defun tj/node-to-src-block ()
"Transform node to src block."
(interactive)
(org-dp-rewire 'src-block t 'append nil nil
:language '(lambda (old elem)
(car (org-element-property :tags elem)))
:parameters '(lambda (old elem)
(format ":exports %s"
(cadr (org-element-property :tags elem))))
:value '(lambda (old elem) (org-dp-contents 'elem t t))))
#+END_SRC
#+results:
: tj/node-to-src-block
Calling this function with point on the following headline appends
the (working) src-block that results from transforming the headline:
* Hello World :elisp:results:
(print "Hello World")
#+BEGIN_SRC elisp :exports results
(print "Hello World")
#+END_SRC
