It's a cool idea, but I'm not sure how individuals would get match performance bonus'. Is this based off KDR/GC ? Or just W/L? If it's just W/L then I'd assume there would be a lot of people with equal amounts of points by the end.
I'd recommend doing this before it reaches 10 000 hits (unless it reaches it earlier then expected) - and try to have it in a monthish. As the history of DP shows, the activity drops off a lot when the schoolyear starts, so it'd probably gain the most interest over the summer. (Also makes the NA/EU timezones less of a problem with more flexibility from both sides).
I personally don't like this idea, since I prefer team vs team. I was never really interested in random teammates. But since I've popped back into the community recently, it seems there's wayyyyyyyy more ringers/pugs etc.. then there used to be, so I'm sure the community would support this idea. This might give more people a chance at winning, too.
I do think scheduling will be a problem. With teams - it's 1 team captain trying to get their team to be online for a time. With individuals it's less organized. Not sure how to make it more organized. And for the 3Eu/3NA in a match, I'd say each week the "home server" (if that event arises) is determined before, and it switches each week.
