We have seen SM and KCM throw FRS
SM is just an amplification of base abilities and while using KCM he just shelves his chakra and uses kyuubi's instead
personally i think it has just got to do with practice
he was finally able to do a single handed rasengan after almost 3 years
so he should be able to throw FRS if not currently then in future
