7. Nikki Bella / Sable
Somehow we have yet to see Nikki Bella going full on heel Sable and flaunt it to all of the male members of the WWE Universe that she's married to John Cena, and can only be lusted after by all of them because they'll never date her. Cena's the company's top babyface, so his relationship to the company's top (in-ring) female heel probably shouldn't be acknowledged on-screen, but imagine if it were! If WWE ever saw it fit to turn John Cena heel, Cena appearing in suits with his very attractive and surgically enhanced god-digger (character) of a girlfriend on his arm would be MEGA heat. Similar to Vince and Sable's pairing at the turn of the 21st century, with Nikki and John, they already have half of the equation set in place.
