I think the Straw Hats win this, extreme diff.

Luffy & Law > Blackbeard

Bonney & Emet > Elders

Zoro & Sanji > Kizaru

Vegapunk & Straw Hats > BB Pirates

NGW Pirates > Buster Call

I ain't ruling out that some Straw Hats could die in the fight.

But sanji 1v1 kizaru

Sanji is High YC Level. Even Aramaki (Low Admiral Level) said that he'd never be defeated by "mere Commanders".

Sanji x Kizaru would've been a massacre.

Oh

Can't Emeth dispel the elders with his Joy Boy Burst?

Yeah, they can.
