Thanks, but this tool already exists:
http://code.google.com/p/include-what-you-use

and we'd like to have it act either as part of a build or stand-alone
with a compilation database. It seems hard to combine the two,
currently.

I'm interested in the Tooling approach because it would cut lots of
boilerplate from our setup and make us less exposed to driver changes.
