You'll probably run out of cpu crunching circuits before bandwidth or anything else. Multipublishing the same onion doesn't really work. Some services do code different onions in urls embedded in their pages to serve as their own cdn/scale but still take the first onion handoff hit. DNS over Tor does work fine with onioncat ipv6, but tor-devs seems determined to break this style of transport overlay with the new HS proposals, without providing a replacement. There is some partial utility in tcp resolvers on the host but it's not as useful as an overlay.
