I might revise my concept slightly, since the idea of a
blind Hyuuga somehow floated on by and stuck (the implications of having a blind child as a Hyuuga would be interesting). I would also like to Gish it up, likely with Tashalatora and Carmendine Monk, but the new challenge is getting blindsight/tremorsense. It would be cool to design a feat for this...

Let's take this from the top. There are some issues with being blind:
1) Precision damage won't work.
2) Can't see, and in the world of Naruto there has to be some compensation or else I wouldn't be able to be enrolled in the academy in the first place.
3) The byakugan sees chakra.
I would imagine this form of blindness to be more as though being unable to see normally, but being able to see the chakra lines of anyone at all times. As a result, probably more vulnerable to genjutsu (what with being extra-sensitive to chakra) and probably blind to things without chakra flows (puppets?).
As to how this can be accomplished, I have no idea.[/spoiler]
If it turns out that it's not feasible, that's fine. More of a mental challenge and less of a requirement, although it'd be interesting to play such a blind character.
