Not on the staff but the ladies scrimmage and play pick up games with male players all the time. I am not sure if Holly still does it but Pat always had a male practice squad that the ladies would go against. They wouldn't just let anyone on that squad though and I don't think there were ever any of the men's players or former players on that unit.
This is pretty common in women's basketball and when you are short on number like we are then it is hard to scrape up enough bodies for 5 on 5 anyway without some sort of practice squad.
