There are several potential themes. First, the theme of identity crisis might be present. Harry, being the one to give birth, would surely question his own identity and how he fits into the wizarding world now. For Draco, his role as the 'other' in this situation would also bring about identity questions. Another theme could be the theme of community reaction. How do their friends, family, and the wider wizarding society react to this? Do they shun them or accept them? And finally, there could be a theme of redemption. Maybe Draco has some past wrongs that he tries to make up for through this new and strange family situation.
One possible plot could be that Snape discovers he has a unique magical ability that allows him to carry a child. He might keep it a secret from everyone in Hogwarts due to fear of ridicule.

He would endure the pain alone, using his own potions and magic to ease the process as much as possible.
