Bad idea! nobody is supposed to own no files at all. You run untrusted services (or untrusted users without account; something like anonymous FTP access) as nobody. This would potentially allow the least trusted entity to change your configs.
Apart from that. Since root can read any file anyways there is no reason to change the owner. And some programs may complain if the configuration is not owned by root.
