Probably. There was some discussions on it lately. Check the
archive.

Let me know if it doesn't work as desired and share your improvements.
I didn't do proper testing as I don't fully appreciate all corner
cases of the use case.
On select tag, you can use it if you like how this document works
#+SELECT_TAGS: latex
* common intro
test
** html intro :html:
html
** latex :latex:
latex
* common next section
Next section

You should be able to test this in a normal org document.
