#+BEGIN_SRC is a part of org syntax, "```" is not.
You will need to modify the org-mode internals to do change it.
Depending on implementation details of org-mode, changing
org-block-regexp and all the occurrences of "BEGIN_SRC" and "END_SRC" in
org mode sources might achieve what you want, but there is no guarantee
that it will not be broken in future versions of org.
