The only way for them to pull that off is if Shikimaru was using Hidan's head as information on Akatsuki. But yeah that woulda been a great idea.... shame this series can never break off and focus on anyone other than Naruto for more than a few chapters or a few episodes. Kishi did switch perspectives quite a bit but it always came back to Naruto instead of him just being one amongst many it was Naruto then someone, then back to Naruto for a long time, then someone else, then back again for 50 chapters, etc.
