Gender Swapping NPCs

While I'm all for diversity, but a lot of leaders, Raven, Marshall Vendri, and Kensaldi are all female. And while she never even appears in the adventure, It feels like this takes away from what makes Kitiara from the books stand out.

I am only in Chapter 3, so Raven is too late to change, but thinking of changing both Vendri and Kensaldi as male. Is there anything wrong with this thinking?
