Your other good option should br Wind main and you can add Gaara instead of Killer Bee .. you can give a decent buff to both Wind Main and Sage Naruto. Your only counter should be Han as he removes buffs and shields. Plus Wind Main got a buff now in 4.0
Go Wind Main - Sage Naruto - Gaara - Roshi with chameleon summon. Gaara's barrier now buffs earth ninjas too so Roshi will be buffed as well .. your wind main will give immunity so you don't have to worry about that.
