Unless I am mistaken, the Byakugan would allow the user to be able to see out of their peripheral vision if they were using Chidori/Lightning Blade.

They would not however be able to foresee the opponent potentially sidestepping it and cutting their head off as they zoom past.

That's where the Sharingan, and it's broken ability to practically give the user precognition comes into play. I've never seen it stated that the Byakugan also had that ability, so while the tunnel vision itself could be resolved, the fact they would not be able to predict where the target is going to move, and adjust accordingly while moving would still be the problem.
