As of now, they are the richest sporting authority, and they can manage things like this very easily without any big concern, even they can manage one ODI tournament as well for women which will create more interest and some better for spreading cricket around India for women talent.
All board may contribute some money and start some sort of league for money, as its not possible for small countries to bear losses from woman leagues. This will only help women cricketers to generate money for themselves, as of now I dont think there is any women cricketer who has earned adequate money from cricket.
