It won't happen. U can't have 2 Orochimaru in the same team even though they're different type.
The best way to revive Orochimaru is thru Kabuto's clone.
In great ninja war there can be 3 teams, so there is the possibility for 3 Orochimarus
But he can only revive from "Sound NInja" in the SAME team, not from different teams.
It doesn't matter how many sound ninjas or Orochimaru you have in other teams. He can't be revived from there.
I hope this helps and clears up a bit :)
