This new plan seems to also have a bunch of holes in it. If the akatsuki end up being freelance mercenaries then at some point they should end up defending their clients against themselves. Also, if they succeed in gaining this monopoly on war and create their own wars to control everybody then noone will have a considerable military force to start a war so they would probably bring peace to all the countries as a whole. If noone is fighting but the Akatsuki thenpeople will most likely find more peaceful ways to settle things.
The leader's plan might also be a big smoke screen to fool all the current members to use their power to get all the tailed beasts in to that statue. While everyone is concentrating on the Akatsuk, Orochimaru and Sasuke will come out of nowhere end up fighting naruto and the gang in a new arc and the Akatsuki leader will dispose of all his underlings and fuse with the tailed beasts in the statue and become the final boss!( ramble ramble)
