I'll start with the first two bolded points; What feats do these hounds have that suggest they can blitz Kisame Hoshigaki from forty meters before he can get off a single technique? Killer Bee, faster than a base Kakashi with his bijuu cloak, was unable to outfox Kisame.

taking the least amount of damage as possible. He has ample reaction feats to be able to detect this attack, and any other trickery Kakashi may attempt with this.
The lightning dog of kakashi was shown only 1 time against deva path.
The distance between them was ca. 30-40 meters and the dog ran very fast in a zig zag course.
The dog was able to reach pain in one pannel

Deva path was able to run away from 6 tailed naruto, this shows how fast he is.

Killerbee in v1 isnt faster than current kakashi.
The sharigan isnt giving the user a speed advatage, it allows the user to react better to attacks which it is able to see, it can cast genjutsus when it looks in another eye, it allows the user to copy handseals and body movements when it look at these, it can see the color of chakra.
Kakashi without the sharingan is still as fast as before.
The chidori a fast stab was grabed by one eyed kakashi without the sharingan active

This shows base kakashis reaction speed with one normal eye.
Now he has 2 normal working eyes, which means he is not handicaped anymore, thanks to naruto.
His reaction speed woud be even greater.
Kakashis food speed is also the same as before

keeping up with 6 gate guy and jinchurikis, ofc he needed the sharingan to react to the fast punches of the jinchurikis

but kisame is no opponent who kakashi need the sharingan for to keep up with kisames movements or speed, kisame is not one of the fastes, normal eyes of Kakashi are enough to see through kisames moves.
Kisame was able to react and analyze killer bees attacks due to samehada which absorbed the raiton and the chakra of the headbut, otherwise kisame had been defeated in the first minute.
Now, let's take into account what Kisame can do to counter it with ease. His hand seal speed is amazing, look at all these seals

to use a mere shark bullet. A Daikodan

, and with a pre-existing water source, is even quicker than having him spit it from his mouth. The raiton hound is absorbed and countered, with a sizable bullet being sent Kakashi's way as Kisame uses Bakusui Shōha.
The difference between beast runner and kisames water jutsus is that beast runner doesnt require handseals, it is a fast shot and even if kisame should be able to preform a jutsu as fast as the beast runner, the dog can dodge the jutsu of kisame with his zig zag course and will land a hit on the orgiinal kisame.
To use Great shark bullet kisame has to concentrate chakra for a long time, his hands are pressed together a few panels before he was able to shot the jutsu

Going underground is useless here. Kisame's able to flood the entire region, despite what you've provided earlier. Kisame was able to keep a

. Doing something similar here is no real issue. With utilizing Mizu Bunshin, any chance at surprising Kisame is gone as each copy can replicate a Daikodan at any surprise raiton attack.
lets have a look at the location again

the water which kisame summons would flow back into the river next to the path.
Going underground will counter a lot of jutsus of kisame, Kakashi is able to go faster underground than kisame is able to create a water dome

Kakashi can also use shadow clones to handle the mizu bunshins
and mizu bunshins have to concentrate chakra a longer time to use GSB, that would take to long against a fast underground attack

The abbreviated version; Kisame's able to react to anything Kakashi can throw at him from the start and respond accordingly. With the ability to utilize a preexisting water source, and able to flood the region he gains the territory advantage. Any raiton is absorbed by Daikodan, with clones being able to keep an eye for any surprise attacks Kakashi tries. Suiton sharks will eventually feast on kakashi. he literally cannot hurt Kisame provided he keeps his distance.
Raiton is to fast for daikodan i proved above
I doubt kisame can react to the fast attacks of kakashi without samehada
normal sharks are blocked with doton
after kisame gets paralyzed kakashi will cut his head off with raikiri kunai
He can fool kisame with a ration clone
Kakashis clones can handle the clones of kisame, kakashi has now the stamina and chakra to do it.
I still think kakashi will win high diff
