A lot players use such lineup. Just place any support as third ninja, and you are good to go. Iruka, Killer B, chiruku, gaara, probably best f2p friendly supports until you get something else. There's no point to talk about another 10k or 20k support ninja yet, since you have a long road. But just to name few, edo itachi and then kakashi susano would be best.
In the end other ninjas doesn't matter, only Sosp matters.
This game is so broken, that only position1 ninja plays in lineup, and others is just for a meat.
