Why wouldn't Naruto try that with Hinata first, just having her become male... or even futa? An opposite sex version of that technique does exist in canon. If Naruto is apparently fertile as a woman with that technique then Hinata might have better luck with the male version and Naruko to have a kid. Also, he's friends with Tsunade and Sakura, one of the best medical-nin in the world and the woman she trained. Hinata and Naruto couldn't go to either of them for fertility problems if it's bad enough? Orochimaru is back to working for Konoha at this point as well isn't he? He even made himself a couple of sons/clones in Boruto. Sure there's the ethical concerns with him, but still he's available.
This is way to short and needs a better set up. Other than that the grammar and wording of the dialogue is off.
