#1 Should not happen - WWE introduces an all women's show
While I am not against the progression of the women's division, the only thing I fear here is that the female superstars will receive bookings just like the Cruiserweights.
Remember how the 205 Live superstars used to be a part of the RAW roster back in 2016 but when WWE launched the Cruiserweight exclusive show, they decided to limit the high flying action to that one show only.
If the same thing happens with the female superstars, then the RAW and SD Live episodes will become unwatchable. Imagine how boring a 3-hour long RAW episode with just all male superstars on it.
The female superstars add variety to the roster and are one of the integral parts of it. So, in my opinion, an all women's show must not be introduced by WWE in 2019.
