You can probably stick that line above into an early-expanded diversion
such as INIT_PREPARE, but none of those are documented, so you'd be
treading in dark waters there.

A probably cleaner alternative would be to let your macro do all of
  rest of your old macro

and document that.

FWIW, gnulib solves things like this by having two (sets of) macros:
one FOO_EARLY and one FOO_... macro.  That's not too bad, either.
