Personally, I think yes. And it must be a girl from Steve. She can become a new motivator for Diana for development. Plus, the source of a bunch of cute moments and covers, for example, where they weave each other's braids. The daughter needs to be introduced being 12 years old (and at the same time, Diana will still look in her prime. 20-30 years), like, Diana returned to Temiskiria for a year, and this year was 12-13 years for her. For which she managed to give birth to a daughter and train her. After which, she returned, taking her with her to teach her to be a heroine. Plus, it can be a nice addition to Superboy/Jonathan Kent (Superman's son) and Robin/Damien Wayne (Batman's son).
