You might consider an ASIS-based tool.

I had thought that Adalog (http://www.adalog.fr/) might have already
done it, but it seems not (worth a look, though; AdaSubst is the tool
I was thinking of).

There are (at least) 2 implementations of ASIS -> XML tools.  I would
recommend my own
(http://gnat-asis.sourceforge.net/pmwiki.php/Main/ASIS2XML) but you
probably want to retain comments, so you might find Marc Criley's
(http://www.mckae.com/avatox.html) more appropriate.

Marc says

  "Given that the Avatox XML representation of the source code
  comprehensively represents the content and layout of the source
  code, there's nothing stopping one from developing a utility to
  reconstitute the Ada source from the XML.

  "Given that, XSLT transformations become available to modify the
  Avatox XML to produce a modified version of the original program."

and of course you need a good grasp of XSLT (probably) and a fair
amount of enthusiasm to contemplate doing the first part!
