Oh god, here we go again. :lol What are you trying to achieve with these threads?
What you are asking now is something that we will never see in the series, and your OP is filled with fanfiction and head canon. Anyone can come up with something else.
Let me tell you the truth. =D
Remember how Sakura was jelly of Hinata's large beast in Road to Ninja? Now her breast are even bigger and she is married to a guy who can create a reverse harem.
Guess what? Sakura's breast also got bigger, they became a good size unlike Hinata's which at this point are just too fat and inconvenient.
Also, reverse harem is useless in NH's relationship, Hinata could barely handle Naruto alone, she would immediately pass out if he ever attempts it.

Remember how Sakura was mad jelly of Ino in part 1 and got mad when Sai called her beautiful in part 2? Now Ino is married to Sai who also can make clones. Naruto likely taught him the reverse harem Jutsu in exchange for getting dating advice from him in The Rest.
Sakura has no reason to be jealous of Ino, quite the opposite, she is married to the guy they both fought for since childhood, Sai is just a cheap copy of Sasuke, he is inferior in everything. :lol
Sai can't use reverse harem, Naruto never taught him and I doubt he can even learn it if he tried. Sasuke on the other hand can use it easily, he was watching Naruto with his Sharingan activated when Naruto used it against Kaguya. And guess what? Sasuke's wife was actually excited, so they are the only couple who can make use of that jutsu.
