I'd love to see Dolph change to a face. I'd have him get tired of Vicky always interfering with his matches with Kofi and dump her, then feud with her for a while and come out a face. As for a heel turn, I'd love a bad guy Mysterio. For his turn I'd have him feud with Dolph again, only reverse the rolls. I'd have Vicky trying to make up with Dolph, but with Dolph saying that it's over between then for some promos for a while. Then for a PPV I'd have Vicky come out during a Rey vs Dolph title match and starts to act like she's trying to make up with Dolph. Then I'd have the ref be taken out for a while and Vicky run in with the belt and act like she's going to clock Rey. Then right before she hits Rey she stops and hands him the belt, and Rey clocks Dolph with it. Rey and Vicky then drags Dolph to the ropes and set him up for a 619, have the ref come to around then, and Rey nails the 619 and gets the pin winning the Intercontinental title.
After the match Vicky celebrates with Rey and they tell Dolph that they're a new Famila and only someone with a true heart of a Guerrero should hold the belt. Then later on Rey cuts a promo saying that while he was out injured he thought about what Alberto was saying about being a commoner and a nobody and that he was right. That in order to become a somebody in this company again he needed a powerful family name to back him into getting the world title again. And what better legacy than the Guerrero's? I'd have him reference that Eddie helped him with his first World title run and that his widow would help him achieve a second no matter what the cost, and that the Intercontinental belt was the first step to his climb to the top. Then have Vicky talk about how she was wasting her time with someone who would never about to a world champ like Dolph. But Rey on the other hand has a shot at the top if he just had a little "famila intervention".
That way Dolph gets a good face push and Rey gets an immediate heel turn with the added heat from being paired with Vicky. I'd have bad guy Rey cheating by using things like steel toed boots for his 619 and hiding stuff under his mask to cheat. And when he goes up to the kids to put his head on them, I'd have him stop and put a paper bag over their head right before he touches their head. Just imagine the tears from kids if something like this occurred. Talk about a ratings hike.
