Honestly I agree with @Thekillman. Kakashi was Hokage until Naruto was ready. But if Naruto wasn't ready, he'd likely stay in the position until a good candidate was ready, which would be Obito.

Shikamaru would be a good choice but he always did want to be more of an advisor to the Hokage.

Sakura would also be a good choice, but I don't know if she'd even want the position.
