I am in the process of creating a new charactor that I think will be a good match for Sasuke. Maybe one day I will put it in a fanfic.
For the existing charactors, SasuSaku will go pretty well. It seems like Sakura's love for Sasuke is more mature now. She was willing to risk her life to protect Sasuke, say before the sound nins and Gaara, especially before Gaara. And Sasuke in a few occassions actually showed caring for Sakura, specially in battle. But, Sasuke's caring is more friendship like.
Sasuke and Hinata would be interesting. They both have prestige blood line. Following the storyline, it is not likely to happen.
