Since other elements seem even more difficult if they're not your affinity and Naruto already used Wind Release very little, my guess it could easily take months, and perhaps he can never do it. if you say this about some other shinobi it might be true but Naruto definitely NOT.he mastered wind release quite early on the difficulty was only about adding it to rasengan.
