The Chidori, if I remember correctly, was a jutsu that brings out/ you use with your maximum speed. Not just being speed. But running with your maximum speed. And that is why it results in a tunnel vision. And that is why the onoy eye that could help in it, is known as the Sharingan.

The Sharingan, just doesn't remove the tunnel vision, but also gives more clarity to everything you see. Basically it would look like you're not running fast at all, for the user that is.

Plus, the Sharingan just doesn't remove the tunnel vision, it allows you to freakin see the incoming movements of your opponent, three steps ahead. Lierally making Chidori safe to use. As the user can even dodge the counter attack of the opponent, even before he uses it.

And I don't think the Byakugan gives clarity to the user or allpws it to track high speed movements, well if anything, not to the extent of the Sharingan. Maybe it's tracking high speed movement feature is the same as the feature of the Sharingan's seeing through things/chakra feature. As in, the Byakugan can see through objects and chakra easily, through far distances as well, while the Sharingan can only see through maybe a single layer against the object(Like seeing underground mine traps, seeing cellular level mini bombs and chakra through walls) While Similarily the Sharingan can track down high speed movements with clarity in perception and predict the incoming moves by just muscle tension. While the Byakugan probably tracks down fast objects but not to the extent of the Sharingan nor with the clarity.

So if you're asking me for the next best thing in place of a Sharingan for the Chidori, would be Sage Mode and not the Byakugan. Sage Mode basically gives the same 360 degree range of the byakugan and the probably the same level of reaction ability of the Sharingan. But still, it won't predict the moves, nor do I believe it will remove the Tunnel vision. But it won't even be a problem, since even visual perception isn't needed for the sage mode(eg.Madara).

These are just my own honest opinion.
