This could be an absolutely amazing match. Of course, they need to be given some real time on the card for that to happen. Both guys have really done well since the split of the Dirt Sheet Duo, as evidenced by their current Champion status (even if JoMo does owe his to Rey Rey's suspension).
With John's high flying tendencies, and Miz's more ground based game, these two have a whole bunch of different directions they could go with this match. JoMo and Dolph put on a damn fine match at HIAC, and I expect better of Miz as a champion. There should be plenty of eye catching spots in this one.
Now, as to the finish...it seems logical that John would go over here...to give SmackDown! something positive going into what appears, on paper, to be a slaughter in the Main Event. I think, however, Miz should win clean. Have RAW win the Main Event, too...and then run this thing to Survivor Series, with SmackDown! challenging RAW based on the fact that all four of their top stars were in the WHC Match. Have another RAW vs. SmackDown! main even, this time headed by the respective champions of each brand (and thus no WWE or WHC title matches, which would be a nice change of pace). At SS, then, you run the Team WWE vs. Team WHC, US vs. IC, and Diva's vs. Women's as three matches to determine the superior brand...
Yeah, I just want Miz v. Morrison II.
Either way, Miz v. Morrison I will kick untold amounts of ass. End of story.
