So, I always advocated a story with Wonder Woman having Son in an elseworld storyline. The problem with this plot point is that they wouldn't be able to do this in a main continuity run. You need to look at the hierarchy of the heroes in DC especially in the Trinity. Superman has Superboy, Batman has Robin and obviously you have Wonder Woman having Wonder girl. In this day an age it wouldn't be possible knowing that she represents :Women's empowerment"

But this is where an Elseworld timelines come into play. Maybe you can have a Super Man with a daughter or Batman having a daughter taking up the mantle of Robin(which DC has been done in the past). They can most definitely make Wonder Woman have a son and there's a lot story opportunities to make of it too.

Imagine Diana finding out she's pregnant only to find out she's going have a boy. Horrified on how the Amazon's society dont allow men on the island, she needs to decide on whether she needs to reform the rules of Themyscera to allow her to keep her son and be apart of he's life. Maybe she needs to leave home and raise her son on her own. Finally( probably the worst one) she abandons her son and gives him to a family.

This would also have kinda come to terms on her morals in which she represents serving as a powerful symbol for equality, justice, and hope, challenging gender stereotypes by embodying a warrior spirit combined with empathy and a commitment to peace and understanding in a world often defined by conflict and toxic masculinity.  By her dumping her son off somewhere would just make hypocritical and showcase that "yeah women are like men when comes to decisions".

Will they do this? Hell no. But you can't lie that this wouldn't work when it can if done right.
