Let's say hypothetically, Naruto and Sakura got together in the Live action series, the Kaguya kitten doesn't happen.
Unlikely. Kaguya may simply not appear if the adaptation doesn't go that far.
As for NS happening in a Western Live action there are three possible ways: 1) Kishimoto is involved as a producer and demands it, 2) director/producer/writer's personal desires, and 3) fan demand.
1) Let us say, that Kishimoto wanted something to finally see if Sakura was really hated like he was told in real time, beyond polls. So he asks/orders the live action to not go with the end pairings and instead follow the story. Which would be NS until the ending. Viewers react positively to Naruto's and Sakura's relationship and want them together, so it happens. I find this as idealistic as it is unrealistic.
2) The D/W/P find the "dreamy bad boy I can fix" romantic trope as well as Hinata's behavior sexist. So refuses them and goes with NS instead. Also, decides for some reason not to go with SNS despite that it would give them huge praise in Hollywood and money from ESG for supporting oppressed "gay coded" couples. This is possible though, I would find it a bad sign as they are less likely to be doing it for the story, as much as their desires that has made a mess of adaptations in recent years.
3) They go with nH/SS but the casual live action audience finds them awful. So to appease them they change it. Most likely, with much irony. Though that depends on how they write it, and D/W/P is willing to go along with audience desire's instead of spiting them.
SS will always have the women who obsess over, "dreamy bad boy I can fix." The reason they want Sakura with Sasuke isn't because they think the story of their romance is good. It is they find Sasuke 'hot' and insert themselves into Sakura while writings their own fantasy romance. They wanted SS canon not because the romance in the manga was good but reinforce their own fantasies. The easiest way to break SS is to present another girl they self-insert into first. So if they start in part two and Sasuke is partnered up with a well received Karin. Those women will insert themselves into Karin instead.
For nH, you would have to make them see Hinata's flaws, instead of the perfect oppressed victim that's entitled to anything she wishes. The Hyuga clan issue or just dragging it out their "romance" with Hinata never interacting with Naruto for long periods, will do damage to nH for a live action audience.
