#2 Naomi
Naomi won the first Women's Wrestlemania battle royal, however, as of now, she is lost in the crowd. WWE creatives do not have any idea about her character.
Thus, adding her in the New Day faction could be an interesting option. She is a dynamic performer and has got all the moves in her armory.
Apart from this, remember, the rivalry that the New Day and The Usos share and since she is married to Jimmy Uso, this could lead to some interesting storylines.
#1 Lana
Lana, the ravishing Russian, definitely has the looks. She posses tremendous mic skills but since her in-ring work is quite underwhelming, she is portrayed in a manager's role.
So, why not add her into the New Day stable. She is very over among fans and definitely has those dance moves and skill set.
Apart from this her addition would certainly rejuvenate the faction and also provide WWE with new storylines and angles.
