fwiw, I use this:
(query-replace-regexp "\\$\\$\n?\\([^$]*?\\)\n?\\$\\$" 
not fool proof (main caveat : it doesn't dtrt when it replaces equations
that are commented out) but good enough for me.

The \n? trickery is the make sure that the begin{} and end{} lines are on
their own line. It sort of works but could be better.
