Well, perhaps there's a plotline where the wizarding community discovers the pregnancy and there's a big scandal. This could lead to Hermione and Draco facing a lot of judgment and having to fight against the prejudice.

Along the way, they face challenges that test their relationship and their will to keep the baby safe.

For example, they could study at Hogwarts while also training in ninja techniques. Along the way, they face challenges from those who oppose the union of the two worlds, like traditionalist wizards and ninja clans. The child also has to deal with their own identity crisis, not fully feeling like they belong to either world, but at the same time having the potential to change both for the better.
