If Naruto continues to train him yes...He does have above average chakra proven by his use of two chakra intensive Jutsu rasengan and Kage bunshin together. Rasengan was made to combine a nature affinity with it not just wind(probably something like Jiraiya's Hellfire Rasengan from the games except more powerful)
I'd think he would go for Monkey Summons do to his clan name and to honor his grandfather...and although i believe the only Summons with sage Mode are the Trio, I think Naruto would find a way to teach him Sage mode anyway...and from the Cs2 forms which are just imperfect sage modes it appears that sage mode turns the user into whatever animal they are most like if they don't have a contract with the Trio for example Sasuke=Hawk, Tayuya=Deer, Jiroubou=unkown(toad,Salamander),Kidoumaru=Spider,Sakon/ukon=Unknown,Kimimaro=Stegosaurus ect...basically what i'm going for here is Saiyan Konohamaru
