#2 To turn Naomi heel
Let me ask you all a question, what do you remember about Shinsuke Nakamura after his last year's Royal Rumble win? The majority will answer the heel turn at Wrestlemania and maybe the No Speak English stint which accompanied the heel turn. While it's not a fault of his own but the creatives, the heel turn certainly made its mark.
Similarly, a heel turn from Naomi could bring a lot of attention towards the duo, both of which were going under the radar. This would also help in creating a mark out moment for the Smackdown's Women's title which is highly overlooked in favor of its RAW counterpart.
A heel turn could give Naomi a new direction and she could continue her feud with Asuka in the upcoming months. It would all depend on the creatives that they could handle her well and don't downgrade her like Nakamura.
