I'm not sure what you mean by "complete recursive expansion". Could you expand on that?
As for replicating the behavior of the compiler, I'd assert that unless &env is precisely what it would be without ahead of time macroexpansion, the compiler's behavior isn't being replicated. The tools.macro library emulates an aspect of its behavior, certainly, and the fact that Clojure's existed this long without anyone doing something like this indicates that maybe this isn't such a huge omission, but without there remains an uncanny valley.
