Look my favorite character is Kakashi, but let's face the facts, he could not face the Akatsuki on his own. He could barely handle deidera, Kakazu and Hidan at the same time, Itachi, not to mention that he died fighting two pains exhausting his chakra. Facing the entire Akatsuki would be suicide. MInato is another questionable one. He definitely has skill and talent, but you're talking about a group in which is a long range bomber, cultist that leeches off of blood, and another that possesses the rinnegan. Minato should have to risk getting into close range with all of these guys, which would be extremely risky considering Hidans technique, Pains Almighty push, and Deidaras long range fighting capabilities. He would be burned out of chakra facing them on his own. Not to mention Kisame who's compared to a tailed beast and Itachi with strong visual prowess
