I'm mixed on my feelings towards this idea. On one hand I'm all for it, because Morrison desperately needs a mouthpiece. He's one hell of an in-ring competitor, but he's loses a lot of credibility when he gets on the mic (or simply because he rarely ever does so). Morrison and Melina work really well together, have a lot of history, and came into the business together, so they wouldn't have to try that hard to make it work. I also like the idea of a Melina and Maryse getting involved in the DiBiase and Morrison feud. Normally I hate mixed gender tag teams, but that would actually be a PPV quality bout in my opinion. What would be really cool, but probably won't ever happen, is if Melina could win the Divas champion before teaming with Morrison, and Morrison could beat Miz for the US championship (since Miz needs to go into the main event, IMO). And then eventually have a mixed gender tag team match with both titles on the line at Summerslam or even on Raw.
Now, the only reason I wouldn't want this to happen, is that I really want to see Melina come back and rejuvenate the Raw divas division. From her interviews it seems like she's really passionate about delivering emotion and passion into a match, and teaching the other girls how to do that as well. She's a great worker, and if she can stay healthy she's one of the best divas we've got. And I would love to see her come back, gauge how well the fans are receiving her, and then figure out if they need to turn her heel or not, because she's one of the only divas who can pull off a heel character and have people care.
So, like I said I'm mixed about the idea. It would be cool if they used Melina right to get Morrison some more mic time and legitimize him a little more. It wasn't too long ago that people were calling for a Morrison World Title reign, and now it's all about the Miz. Maybe Melina can get him to that place again, who knows...
