A free mod for Mount & Blade II: Bannerlord, by tase.

Mixed Gender Troops is a mod that adds female versions of each combat troop, depending on the settings. For example, if the setting is set to create a female version of all units, then a female version of the swordsman will be added, as will the female versions of the other troops. The same applies the other way around if the setting is set to create a male version of all units. The troops themselves will remain the same, but their equipment, recruitment cost, required experience, and level will be different for each gender. The settings are accessible through the in-game menu. The effects of the mod won’t be immediately apparent, and it will take one day to see the changes. The installation of the mod is also accessible through the same menu.
