This isn't going to have the desired result
It will make tracking harder for about a day, assuming the ad companies fall asleep at the wheel, before they switch to another method that works. Long term all this will accomplish is to make it harder for users to see what's going on and frankly, cookies are too hard for most users to make any sense of anyway.
I think it would be a better idea to have a think about who is going to pay for the web, users or advertisers, and after that amazingly short discussion, how to design a system that allows the advertisers to target a particular audience with a high degree of confidence that doesn't require them to maintain a database of individual users, which of course raises even more questions about who would host and be responsible for such a system.
On second thoughts, I believe cookies are the lesser of many evils.
