Another combo: Kiba's Fang Passing Fang with Lightning Release Chakra Mode. The lightning chakra already has a piercing quality to it, and FPF is all about piercing. Similarly, Fang Rotating Fang with the Wind Release equivalent, since the rotation in that jutsu is more about cutting.

I would have liked to see more jutsu involving blood. There's all sort of symbolism with blood. The idea that immediately comes to mind is Sai's drawings. Wonder how it would affect them, using his own blood instead of ink, or just adding a bit of his blood to the ink. Maybe it would give Sai greater control over them. Maybe pull a Hidan, and use his opponent's blood. Could be a way to create a great tracker jutsu. Make a blood bloodhound, that can track a target because it seeks the blood it was created from.
