In theory yes it could. There would need to be a few changes made and thinking
about this I wonder if this is a good idea. It can be done.

Another maybe simpler method is to add an option called --only-download which
internally enables --dry-run but allows the downloads. The downloads only
happen if the source is not present. This however does not work if the code is
in git or cvs and the URL indicates a pull or update. The downloader will
attempt to access the internet in these cases. I suppose you could then use
--no-download to suppress this.
