I doubt that would happen.
Akane herself stated her goals and focused her will around that goal a few updates back, where she was meditating with Azula.
She said that she will rule the world with an iron fist, and anyone opposing her would be cut down but those supporting her would have a good life. Anonkun's player base built it around that and the bases for it since the beginning. Which resulted in the current villainous imperialistic and perfect Crown Princess Akane.
The element of Fire is that of Will and to be honest, I don't see any relevant or sufficient enough reason for Akane to drop her ultimate goal nor for the Anonkun player base to do so after working to reach it for like 60k words long?
I doubt Azula would have any kid, Akane seems like she would be lenient enough to allow her sister to not marry if she wished to and Azula in the canon universe just kind of went power-hungry crazy, really. I just can't really see her marrying anyone. I mean, can you imagine her caring for a kid? Or just not fighting or training for 9 months?

Impossible.
So, unless Akane goes for the sperm donation, she'll have to rely on Zuko to perpetuate the line as he did in the canon universe.
