Raikage and Killer Bee could each potentially take this alone; putting them together and giving them Darui and Shee gives them a massive advantage they don't even need.
The main issue is that the Sannin have nothing to really hurt them barring Frog Song which they'll never have enough time to prep. Yomi Numa won't do anything to the walking piece of Raiton chakra, and Killer Bee also is proficient in Raiton; Doton's natural superior. Orochimaru's snake and Kusanagi attacks aren't hurting them either; we've seen Kusanagi fail against KN4 (thus Bee's V2 8 tails should fare comparably well), and we've seen Sasuke's Chidori Kusanagi literally bounce off the Raikage's shoulder when cloaked.
Meanwhile, nobody on the other team can react to Raikage or Killer Bee's cloaked speeds. Raikage could flank MS users and tickle Minato's nose with his fist and force FTG, and Killer Bee has shown to be able to keep up with cloaked Raikage in base, let alone in V2. The Raikage could very easily flank and behead Jiraiya, and then beat down Orochimaru until his chakra runs out from continuous Oral Rebirths just to stay alive.
The Sannin can bust out summons / Hydra mode, but then that will just prompt Killer Bee to go Bijuu Mode and nuke them off the planet with continuous Bijuudama spam.
