I don't think it's so weird that he would use Gentle Fist, which could be thought of as "Hyuga-style taijutsu," even if he lacks the ability to perfectly strike tenketsu without the Byakugan. It's still an effective form of taijutsu, certainly more disciplined than Naruto's. He could also always develop unique methods to make the techniques more effective, similar to the way Naruto used Kage Bunshin to perform Rasengan.

For what it's worth, I'd love to see him use a Rasengan / Palm Rotation combination technique.
