I would love to see all four of them in the ring together since they all have evolved since 2015. All of them have different characters. They are solid main eventers on both brands. Why not do the dream match at a WM. We don't need Sasha vs Charlotte again since we have seen that too many times. Same goes for Charlotte vs Bayley and Charlotte vs Becky. This match at WM would be main event night one or two potential. This is not me being biased. This is me seeing where the money is at. The money is between these 4 awesome talent and awesome wrestlers. Those who say they shouldn't are talking out of their rear ends.
Think about it this way. They are not going to be in the WWE forever. This would make female wrestling fans happy, combined with all of the four horsewoman fans. The last time we seen these 4 compete against one and another was NXT Takeover in 2015. Do it next year if Ronda vs Becky is not on the table anymore or Charlotte vs legend, same case for Bayley and Sasha. Just think about it as a business standpoint.
