In fanfiction, Luffy often shows his leadership by making quick decisions in battle. For example, he might decide on a sudden change of strategy that surprises the enemy and gives his crew an advantage. He also stands up for his crew members no matter what, which is a key aspect of being a good captain.
Their relationship might become more of an equal partnership in terms of strategizing. Usually, Luffy is more about action, but a smart Luffy could contribute intellectually to Robin's plans, making their bond stronger as they rely on each other's skills more evenly.
I'm not sure if there is a specific fanfiction about a female Luffy being pregnant. Fanfiction can cover a wide range of creative ideas, but this might be a rather unique and perhaps not as common concept within the One Piece fanfiction world. It could exist, but it would depend on the creativity and interests of individual fanfiction writers.
It might not be exactly what you need, but I'll try my best to recommend a novel that is most relevant to your description: "Beautiful Man: I, a native, the godfather of superheroes" is a light novel by the author, Unbridled Beauty Green Plum Wine. It's a derivative doujinshi novel. The general plot of this novel is as follows:
Enke had traveled through the Marvel Universe and obtained Compound 5 replacement system! As long as it was a valuable item, it could be exchanged for points to exchange for all kinds of powerful #5 compound!
At the beginning of the fusion of Compound No. 5, he had obtained the ability of a native. In order to obtain more valuable items, Enke directly chose to bring Captain America to join the army!
Thus, an invincible superman appeared on the battlefield!
Smashing a tank with his bare hands! His hot vision swept across everything!
It flew across the entire battlefield!
All the countries were stunned, and so was the Hydra!
How did this monster come out?
Captain M: I already said that he and I are both products of the super soldier serum. Why don't I believe it at all?
…
It was not just the ability of the natives. When Enke showed more of the ability of Compound No. 5, everyone was numb!
Tony Stark: What the hell is this Steel Body? I think he's Iron Man, right?"
"Teleport with people?" Magneto asked. Realization? This is the god of the mutated humans!"
Black Marinated Egg: "Stop talking. The Fu Lian should disband on the spot. We can't beat his Black Robes Public Order Squad!"
Enke stood above the Empire State Building and looked down at everything. I'll do whatever I want!"

Well, in most cases, Luffy would use his unique abilities. He might use his Gum - Gum Pistol to knock out the bad guys. His superhuman strength and speed would allow him to reach Nami quickly and stop the assailants before any harm could be done. Luffy's sense of justice and loyalty to his crewmates are so strong that he would not let anything bad happen to Nami.
The shared ideology might be another factor. Both Luffy and Dragon seem to oppose the unjust systems in the One Piece world. Luffy wants to bring freedom to the islands he visits, while Dragon aims to topple the World Government which is often seen as corrupt. So in fanfiction, this common ground can be exaggerated to make Luffy more like Dragon.
In fanfiction, Luffy might be more strategic in some cases compared to the original story. While in the original he often charges in head - first, in fanfiction he could be shown to think a bit more before acting in certain situations. This gives a different flavor to his captain - like behavior.
There are many good novels about the male lead is the captain that can be referred to in the following popular genre:
1 Star Cowboy: This is a classic sci-fi adventure novel about a captain named Dennis Dufresne on an interstellar journey.
2 " Three-Body Problem ": This is a Chinese movie in which the male lead, Ye Wenjie, is a captain. He shows extraordinary courage and wisdom in the face of the crisis of alien civilization invasion.
3. The Galactic Empire: This is a science fiction novel written by the Soviet Union's Ivanovic Zamiyadin. It tells the story of a captain named Yuri Gagalin during the Second World War.
4 Black Hawk Down: This is a novel written by the United States. It tells the story of a captain named Jack Thorne during the Second World War.
The above novels are all good representative works of the male lead is the captain. The readers can choose according to their own preferences.
Luffy will most likely use his Gum - Gum abilities. He could stretch his arms to grab Nami and pull her away from the abuser quickly. For example, he might use Gum - Gum Pistol to knock out the bad guys who are abusing Nami.
Well, a plot could revolve around Luffy as a girl having to deal with the expectations of femininity in different islands they visit. Some islands might have strict gender roles, and she has to find a way to balance being true to herself as a fearless pirate while also navigating these cultural differences. And perhaps her crew helps her in different ways to overcome these obstacles.
