Perhaps, Kakashi would be a better teacher for Chika Nara then Sakura.  After all his father was the White Fang of the Leaf.  Also he was able to help Sakura, if only a little by teaching her the release.  Also then Sakura could teach Hinata some medical ninjutsu and Shino some medical ninjutsu.  Thought it's not my place to make those judgements.
