4 against 4

let's choose a table, agree on time (yes time zone problems) and play 4 players against 4. You can not change sides after the war is declared. And, naturally, everyone playing should now that it's a special game, so no "we 4 against whoever comes here"(=pga). Flagging can be performed as a whole time. People could create new aliases for this, if they are worried for their points and ranking.

So, would this be wrong? Of course, it takes one table out of "public" use to play this special thing. But I'd like to hear comments about this. It might be a bad idea, since I haven't thought about it for weeks etc. But that's why i'd like to talk about it.
