You can at the very least set the level manually:
#+BEGIN_SRC elisp :results output raw :var level=3
...
by just eyeballing where the source block is in your file.
I think that's easy and does not require any programming.
You just have to remember to change the level when you cut
and paste the code block to other places.
There is org-current-level though if you want to go that way.
