Konoha Proxy.

All those lineups look solid, though I do think the Kushina lineup will probably work the best due to his passive which goes very well with Kushina's kit. I think the 3rd one will work best, you have barrier + kushina buffs + cc and every round you will have a mystery available. I'm personally not a big fan of this Minato but his mystery can be very effective and I think with this you could win against kakuzu with ease, assuming you get his mystery off of course.

Edit: I also recommend you try using Fire Main's Sealing Jutsu, that team has many dodges or kushina which is immune, sealing can help you against so6p naruto, edo mianto etc.
