My ideas concern more with the role of women in-game.
Women should be able to level up their ability to gather resources efficiently, which also changes their clothing, like how soldiers and healers level up their stats and acquire new clothing. This makes women at least more valuable game-wise, instead of disposable worker unit types. Women would still be vulnerable to attack, therefore not overpowered.
Women should be able to set up devotional offerings in front of temples, at the cost of resources on a percentage on-going basis, which can grant passive non-permanent buffs to stats for units in home territory. The buffs would be gone as soon as the offerings are cancelled or there are no resources available, and the scope of the buffs is in home territory, therefore it is not overpowered. There are already similar in-game mechanics to this, with the Druids (warriors have buffs when near druids) and Roman Citizenship (Roman faction have non-permanent stats in home territory).
All of the mechanisms are also historically accurate, women did have vital roles in managing local economies and temple worship in nearly all civilisations.
