The Twin Vipers will have none of the levels of their constituent Vipers. The only reason to rank up either Viper would be to earn the Mastery points for Viper levels. Note that you only get Mastery from leveling up a given weapon type one time (leveling up a Lato when you've already leveled a Lato before gives you nothing), so leveling up both of the Vipers is pointless.
