Being an Indian, I am a bit more skeptical about the future of the WIPL. Even matches involving the national women's team doesn't get a good response within India. In Australia, the women have a lot of interest in sports and a lot of them follow women players such as Ellyse Perry. But here in India, women are more interested in TV sops and shopping, rather than in sports. Among my female friends, there are only a very few cricket fans.
But that doesn't mean that BCCI can ignore the women players. They need to start the WIPL, latest by 2021.
Its worth giving a shot IMO, earlier the better. I am also not sure about the viewers we would get but its worth giving a shot. People here love cricket so if the tournament falls off from or doesn't clashes on with gents cricket team schedule, I think it should be fine.
BCCI can try with one season and see how much successful it gets.
