I remember all the "Yondaime is alive and is the leader of Akatsuki" theories before we found out the truth and about Pain lol that was so long agoThat would be pretty awesome, but imagine Minato in the Akatsuki. O-o
kakashi's chakra and staminat is so good and better than itachi's onenot at all. All akkatsuki members need to have enough chakara to battle/extract a tailed beast. Kakashi doesn't have that amount of chakara. All he could do vs the 6 beast is doge. He would need to have his partner preform/ battle. He would have to have some sort of forbidden jitsu that allows him to constantly drain an opponents chakara. Then he would make an excellent member.
(currently) Best paired with Zetsu. Because the wood would give him much more stamina/chakara. Would allow him a 2nd kegigenki, more kumu's, a larger chakara pool, allow more copying and he is smart enough to really take full advantage of Zetsu's unique traits..... plus Obito could keep an eye on him.
kakashi's chakra and staminat is so good and better than itachi's oneAlthough he would fit due to his skill,i do not think he belongs there,because every akatsuki member had his own uniqueness e.g hidan and his immortality,nagato's rennigan,kakazu's stings or veins and his ability to use different elements.Which made them complete monsters in terms of power which also deceived their appearence.
But i believe this is not in kakashi's case.He is known for his intelligence in battle,and varies of ninja skills that he possess.He does not have any skills that trembles fear in the enemy such as itachi's susanno etc.Although he does have kamui but it leaves kakashi in a very vulnerable position after using it.Which is also effected by his low chakra level.
There is another theory of mine which explains this,kakashi's chakra and staminat is so good and better than itachi's one
