Yeah they could. BM Choji would stop the meteorite. 7G Lee would cut half of the meteorite assuming it is his strongest form. Byakgoku Sakura would finish the other half. Sorry but two is overkill. With perfect teamwork I don't see why they wouldn't be able to stop the meteorite.
what's with this thread,lee already destroyed something of similar size with sixth gate of joy. choji could hold it off if he grows big and sakura could destroy 1/100th of the meteor
