Sasuke and Hinata...both full advanced bloodline characters...their offspring would have the Sharinkyuugan...Byakuugan (spelling? i think it's right...) with the ability to copy an opponents moves while using gentle fist techniques...also, eliminates the blind spot of the Byakuugan (Neji's weakness during the 4 sound ninja fight)...downside: user loses the Mange Sharingan Technique...but look at what you would gain: Sharingan (copy techniques, and f*ck with peoples minds), and Byakuugan (pinpoint Chakra holes, Gentle Fist Style, and no blind spot!)...that would be a badass character...
