Maybe this idea could be incorporated in a more extended tech tree, where the players chooses (and has to stick to) their prefered advantage. Perhaps imunity from cov ops could be another one - where the power of cov ops are more destructive. Then there could be a further resource bonus, and another production bonus etc. Whether someone has the time to modify the tech tree and to modify nearly every apect of the game is another question though.
