Theory suggests to me that this isn't necessarily the best approach; load balancing should be based around server response times and traffic volume rather than requests.
That said, if all you have is those logfiles, you'll need the hostname of the server in there; that's what makes the vhost report work. You can use VHOSTREPALIAS to change the name of the virtual hosts provided they're in the file already, otherwise you'll have to write some <insert-your-favourite-programming-language-here> code to add them in.
