Summons can be ninja dog and white serpent in replacement of the golden serpent and dog of hell.
For Dog of hell and Ninja Dog you can interchange the talents Earth Style Sphere of Graves( will give you 9 total combo but GNW kankuros mystery wont have a chase from the other ninjas) and Primary Lotus (which will give you 8 Combos but has an active chase of the other ninjas when GNW kankuro uses his mystery)
