Nova - great idea, and I regret we didn`t think of something like that a while back. However... (and I know I said this before

) - I think a solution to all our problems is just 1 month away. We just arranged a huge promo that should see 10,000+ copies of the game go out with-in a month, and in addition unless something totally unexpected happens we should be on Steam in early December. So far each Greenlit game went through "Top Selling 10" games on Steam - that`s usually 1,500 new players per day...
So we`ll wait to see if higher player pop will fix PvP mechanics without a need for extra work on our end (rather work on Siegeworks right now

), but if all that fails - your approach would be the right way to go.
