Another plot point could be how she deals with morning sickness while on the ship or in the middle of an adventure. It would add a touch of humor and also show the difficulties she faces. Also, her relationship with the crew might change. Some might be protective of her, while others might think she's no longer fit to lead.
The conflict between her old life and the new responsibilities of motherhood would be interesting. For example, she might get an offer for a big and dangerous pirate raid but has to turn it down because of her pregnancy.
One possible fanfiction could be where Isabela discovers she's pregnant and is initially in shock. She might try to hide it from her companions at first, fearing their reactions. Maybe she's worried about how it will affect her freedom and her life as a pirate. But as the story progresses, she realizes she can't keep it a secret forever and has to face the situation head - on.
One common theme is the reaction of Isabela's friends and allies. For example, how Hawke might support her during this time. Another is the exploration of Isabela's own fears and hopes regarding motherhood, as she is a complex character with a carefree exterior but may have deeper insecurities when it comes to bringing a new life into the world.
Another plot idea is how the different factions in Dragon Age react to the news. The Dalish elves might have mixed reactions. Some could be overjoyed at the prospect of a new life, while others might be worried about Merrill's situation, especially if she is in a relationship with a non - Dalish. And the templars or mages in the Circle could see it as a threat or an opportunity depending on their stance.

Another great plot point is when Naruto has to face the darkspawn. His ninja skills and his ability to never give up are put to the test. He might have to team up with the Grey Wardens or other Dragon Age heroes. This combination of two different heroic archetypes - the ninja and the Dragon Age warrior - makes for some really intense and thrilling scenes. It also shows how Naruto's values and way of fighting can be adapted to the much darker and more medieval - like world of Dragon Age.
A fanfiction could also focus on Isabela and Hawke teaming up to help the people of Kirkwall during a difficult time, like a famine or a plague.

This would show their altruistic sides and how they can work together for the greater good.
