#5. Lacey Evans
Lacey Evans is currently a free agent on the main roster and has not been assigned to a particular brand, however, in her official debut on the main roster, Evans did compete against Raw star Natalya in a dark match and has also been making cameos over on the red brand.
However, having entered the Women's Royal Rumble match at #2, Evans did make a lot of impact on what was her first Rumble outing. 'The Lady Of WWE' also scored two big eliminations when she got rid of The IIconics from the Rumble match before being eventually thrown out of the ring by Charlotte Flair.
Considering that Evans was in a confrontation with some of the top female stars from the SmackDown Live roster, it would make all the sense in the world for her to officially join the blue brand and maybe challenge The IIconics or Charlotte Flair to a match.
#4. Nikki Cross
Known as NXT's twisted sister, Nikki Cross has had quite the impact on the main roster, where she has competed in a match for both the brands. Cross' initial appearance was under SmackDown Live where she went toe-to-toe with former SmackDown Women's Champion, Becky Lynch. And few weeks prior to the Rumble, Cross teamed up with Natalya and Bayley to defeat The Riott Squad.
At the Royal Rumble, Cross lasted around 9 minutes before being dumped out by The IIconics. I personally feel that it is about time for WWE to officially assign Nikki Cross to the SmackDown Live brand where she can join Sanity once again and run roughshod through the entire roster.
With Becky Lynch now drafted over to Raw, SmackDown Women's Champion, Asuka is in need of a fresh new challenger and Nikki Cross could very well be that new challenger 'The Empress of Tomorrow' has been waiting for.
