Would work.  Whether it is a better solution or not, it depends.
While referrals are a standard, back-ldap and significantly back-meta
are not (back-ldap would be of little help in this case, though).
Moreover, back-meta is far from stable; I'm using it without appreciable
problems, but I can't affirm it is bug free.
However, it would surely achieve your goal, that is moving most of the
network traffic to the server side.  You may also exploit some
of its rewrite capabilities.  Be sure you carefully read the examples 
and the document in librewrite if you need to do anything but a plain
installation.  Feel free to ask further details.
