Not quite, unfortunately. Apache's not all that nimble; setting up rewrites for a handful of ips-and-methods is pretty easy, but it doesn't have a built-in way to use an external list of ips (that I'm aware of). I just checked, there are over 1300 tor ips in the result set currently.

I could write a conf.d file to be included in each vhost, and write a script to generate a large rewrite file nightly and "apachectl graceful" it afterward, and that would probably work... but I expect that will have a measurable impact on response times and, again, I'm not hosting governmental sites or anything that could reasonably be considered vital to the health and well-being of innocent tor users.
