As always your threads are a pleasure to read,you back yourself up with facts unlike most of the people out there.
Now for the match ups I can agree up to a point,but I think you're underestimating some of the kages.
-1) Itachi vs Second Tsuchikage - I agree that the 2nd Tsuchikage can't defeat Itachi,throughout the manga it was proven multiple times that Itachi is a pretty strong shinobi.Muu could use his splitting technique for amaterasu,but when it comes to susanoó I'm afraid he has no way of countering that.
-2) Kisame vs Second Hokage - There isn't enough info about the 2nd Hokage,but Kisame (with samehada) has chakra levels close to a tailed beast and I doubt the 2nd can do much against him.
-3) Hidan vs Fifth Mizukage - I think you're seriously underestimating Mei as she has some pretty badass jutsu's.Hidan's weakness here is that he's a close range shinobi,where Mei has plenty of mid range justsu's like lava release and that acid mist jutsu.If Hidan can't land a hit on her in time,he's most likely gonna be melted by the mist.
-4) Deidara vs Fourth Hokage - This can go either way.The only way Deidara can win is if he uses the C4 jutsu,but Minato has FTG,so if he manages to land a seal on him( like he did in his fight versus Tobi )before the C4 jutsu is ready,Minato will more than likely end up victorious.
-5) Kakuzu vs Second Mizukage - This definitely goes to kakuzu,he has fought hashirama and lived,plus he's shown intelligence on par with Shikamaru,so I don't see the 2nd Mizukage winning this one.He can also combine his elements for powerful combo attacks with which he can bomb the Mizukage from multiple directions.
-6) Sasori vs Third Kazekage - Sasori has beaten him before.
-7) Zetsu vs Fifth Kazekage - You're underestimating Gaara.He may be young,but he can put up a pretty good fight against Zetsu.The spores could probably be countered by Gaara's sand armour ( the one that covers his entire body,not the shield that automatically protects him ).If so then Gaara will most likely win.
-8) Nagato vs Third Hokage - Hiruzen even in his old age was pretty fast,Nagato lacks mobility.This one's a draw since Hiruzen will need to sacrifice his soul to seal Nagato with the Death Reaper seal.
-9) Konan vs Third Tsuchikage - Onoki will most likely win.There is a huge battle experience gap in his favour .
-10)Tobi vs Third Raikage - I can't decide on this.Probably a draw.
.... You are right in a lot of examples. I wonder what will happen if all 10 are fighting against the 10 hokage's! I think if all 10 akatsuki are in a battle ground! no one might stand a chance lol (together)
