I have read about someone who designed gender neutral cards, replacing K Q and J with gold, silver, and bronze. Another way of doing it with existing cards is for the dealer to announce (before dealing the cards): “God Save the Queen”. This would mean that for that hand, the King and Queen change places in priority, i.e. the card value would be: Ace, Queen, King, etc. This could be done in games such as bridge or poker, more generally any game in which there is a dealer.
