Count me in... but in reality it'll probably end up being just ICO vs Modders.
Well when I thought of the title that's basically what I meant, but who knows, maybe we can Tyr out of retirement with Aquia (sorry if I misspelled those names) and someone else that is at the very very top. If that ends up happening we'll certainly need it to be a 3v7, maybe with an additional handicap too, just to keep the game from being a total slaughter. 
Second game would be pros and modders following normal 5v5 pug match rules.
Maybe in this way you might get some modders to play MP online in the future.
Didn't think about just using the Plug rules, I suppose that's another way to do it.
And yes, the idea is to hopefully get some good exposure for both communities, ICO most directly in this case (they probably need the help more), but if we ever extend this to mod matches as well that could also get the mods some attention as well.
The teams should be stacked enough (in favor of the modders) for the outcome to not be certain at the beginning I think. 3v7 or something.
Yeah, I was thinking a 4v6 at first, but depending on how many people sign up and how confident you ICO players are we can certainly do 3v6 or 3v7.
Too bad Sins doesn't really allow spectators, as I would like to see this match in action.
If this this ends up happening I'll give in and finally get Fraps (I was planning to get it for Christmas but in this case a little early present is justified I think ), so I could record it and put it on YouTube. Granted you'll only get my fairly noobish perspective and commentary, but we'd probably put up the replay too.
Hmm, perhaps this could be a best-of-three series? One game without mods, one with, and the other the result of a coin toss?
If its a success we can certainly try doing this more often, and discuss which mods to use if the MP players are willing. If this ends up becoming a fairly regular thing we can even alternate Vanilla - Mod1 - Vanilla - Mod2 etc., letting additional people participate each time.
