So, you'd have really limited choices, wouldn't you?
Gai-------Not exactly the brightest, Strong, Cares about furthering the "power of youth".
Asuma---Dead.
Kakashi--Dead
Tsunade--Dead
Shikaku--Smart, Calm, Strength in battle (unknown)
Kurenai--Smart, Strong genjutsu user, Caring, Mother.
Ton-Ton--It's a piglet, obviously wouldn't be a smart Hokage choice.
Shizune--More of a Medical Ninja than Hokage.
Elders----Smart, logical, but stuck in the ways of the past.
Naruto---Already turned down the Hokage offer.
Itachi----Would make a great choice, but he's not part of the village anymore, and he's kinda already dead, and would most likely die after the new and improved Kabuto dies, because the jutsu wouldn't be active anymore.
In my opinion, either Kurenai or Shikaku would be the next Hokage, logically speaking, but considering the fact that Kurenai is now a Mom, i think that she would have way too many responsibilities and wouldn't accept the position. Shikaku would be the smartest choice, or at least I believe so.
