srr didn't notice this earlier.. was in finland at the time...
as for your question, if you don't know how to change the source code yourself, you can't
as with the anope core, changing the source code of any of my modules voids your support, and the changing itself will not be supported either.
And for the record, the commands don't make new data available, users can always get the version of the services you are running, even without that command. (Just send a version request to the services server.)
