Forcing mtime would need to be done by Trebuchet during deployment. Varnish does not have shared state as far as I know, so it will not be able to hide the mtime differences. While it might be possible to do it via trebuchet, I would prefer to remove etags, push for a very large caching time and have a clean cache busting solution (https://gerrit.wikimedia.org/r/284428).
