I think it's a good idea but that should be added in another category.
like maybe clan wars without clans that randomizes the teams, I mean it doesn't really make sense but if we can be a little more creative here it can be something I suppose.
Also it can be added to weekly competition like the player with the best winning k/d and most points.
Another thing that could be fun is to fight your own clan, let's say there are 4 players so maybe fight your own clan 2v2 and the teams are randomized just to have fun with your clan mates I guess.
these are just ideas that needs more thinking of how to make it possible and fair and also not to make it look like swap or whatever.
