In one tool? That sounds prohibitively complicated. Why not use one tool for
preprocessor rewriting and another for C++ rewriting?

Python and perl certainly do, via named backreferences as well as, I think,
numeric backreferences with \g{10} and such.
It sounds like you could probably hack a preprocessor-rewriting into one of
the open-source preprocessors such as MCPP. It's just too much scope-creep
for a C++ rewriting tool[
