#4 UFC Invades
There's been a ton of speculation about the WWE signing Ronda Rousey, and even more speculation about a pro-wrestling deal being made with Connor McGregor. If these two did sign for the WWE they'd have a plethora of UFC talents.
What if they ran an invasion angle? They could use Rhonda, Shayna Bazler from NXT, and the rest of 'The Four Horsewomen' from UFC to take over the WWE Women's division, and bring in Connor McGregor, and the Irishman and Brock Lesnar could hold down the two main titles on Raw and SmackDown LIVE.
You could even go completely nuts and have Dana White reveal himself as the mastermind, starting a huge battle for control of the WWE between the WWE Superstars and the UFC stars.
Okay, so it's unlikely that'll all happen before Christmas, but we could at least see the match that was teased at the Mae Young Classic between the Four Horsewomen of the WWE and the Four Horsewomen of UFC.
