Kidōmaru combined with Tayuya is a deadly duo. You're pretty much underestimating them.
Also, saying Jirōbō is one-shotted with a punch, you obviously have not seen him lifting an over mountain-sized Chōji with only one hand. His power is easily comparable to non-Byakugō Tsunade if even Byakugō.
Sakon is not needed, although he can be a Bukijutsu support for Jirōbō. After few moments, Tayuya starts binding, while after that she summons Doki. They drain her immense strength, leaving Tayuya even no need to bind her. Kidōmaru's webs, which can hold elephants, can easily restrain her and a Kumo Nenkin boomerang to cut her head off, or V2 state of Kumo Senkyū: Suzaku of killing her with an Arō.
Also, Shikamaru noted Kidōmaru's skill and intelligence prowess to be easily enough Jōnin-level. He is also the smartest shinōbi from their team.
That's exactly what you're doing here with tsunade.

Sakon and ukon are a non factor. They couldn't even handle sasuke in taijutsu, who was a 2.5 at that point, with his sharingan off[

Doki are going to drain tsunade's strength? Can you prove this? Because, from what I remember, they couldn't even drain shikamaru's strength. Shikamaru sucks at taijutsu(1.5), i.e worse evasion abilities; Has a far lower speed stat(2) than tsunade; and is a stationary fighter, yet doki couldn't

. Again, shikamaru is complete rubbish at taijutsu, so his CQC tactics, evasion and all around prowess would be of a far lower standard than someone like Tsunade, guy, rock lee, etc. Nothing suggests these doki can land a hit on tsunade, and one hit from her would send them

Kidomaru's the only challenge here, but like all the other sound 4, you guys are just overrating him. Neji's a completely stationary fighter with quick handspeed. The way his fight with kidomaru happened isn't how it'd happen from the start. He wouldn't even make it past a CQC like

. In fact, he only went long ranged when he realised

. But, unlike neji, tsunade's not going to let this guy just dash off into the woods unaccounted for. For that matter, from the second tsunade starts to notice these random snipe attacks coming her way, what do you think her first move would be? Obviously to get rid of his hiding spots in the forest. This guy would be left a sitting duck out in the open.
Claiming his webs can even hold tsunade is an assumption by your part which is backed with 0 proof. Out of all those guys, the strongest person(brute force) was neji. That's not enough evidence to state this guy can hold a woman who can lift massive metal swords or smash the earth with her finger.
*no, jirobo can't catch tsunade in his dome. Tsunade can simply jump out of it, or smash it with 1 punch.
These guys are outclassed and outmatched. They'll never win this. Tsunade doesn't even need byakugo. And, if she decides to use it, all hope of victory is instantly gone.
