Agreed - a large part of the huge growth in player base for at least 5E D&D is diversification from the classic "white nerdy geek guy" player base - and that new player base is probably going to be looking for representation. I can say as someone who sells minis online - judging by the names about 30% of my customers are female, which is far more than I anticipated. That said - it is the cliche models which by far sell the best.
