I don't think this patch is a good idea, as it mixes elements from
different types: LaTeX fragment (inline), and LaTeX environment (block).
For example, the regexp you modify is used as a paragraph separator,
which doesn't make sense for inline LaTeX.

As a reminder, Org does not claim to support raw LaTeX syntax besides
very simple constructs. If you want to insert elaborate LaTeX code, you
can always use:

    #+begin_export latex
