I don't see the point. Varnish usually runs on separate servers. On a
small scale setup, the likely improvements would be negligible. The Varnish
developers also do not want Varnish to become a web server, it's just
not it's job.
Your time is better spent improving your cache hit ratio (% of requests
cached) as well as integrating purging with your content management
systems when caching dynamic pages.
If you are serving flat files only you may want to consider just using
lighttpd or nginx, which are known to be fast.
