In my opinion Kido in general is irrelevant and Ichigo learning any would just be a waste of time. During the SS Arc it had a few badass moments (Byakuya's Rikujokoro on Renji and Byakurai on Ichigo; Aizen's Kurohitsugi), but beyond that Kido has almost become a joke that gets broken or batted away with ease. Not to mention Ichigo's fighting style doesn't really support the addition of Kido.

Also, let's not forget that Ichigo's never been renowned for having decent control over his reiatsu. Even if he were to try learning, I could see him only being as adept as it as Renji and having it blow up in his face every time.
