As of right now, I don't think so. There's just too much going on or about to be going on in both the WWE & World Heavyweight Championship scenes.
For instance, the latest rumor is that the Sheamus & Daniel Bryan feud might wind up lasting through much of the summer. Then, there's also Alberto Del Rio waiting in the wings, plus there's also the possibility of Del Rio & Bryan being involved in a three way feud against Sheamus. At any rate, it's my assumption that the WHC picture is going to be well occupied for months to come.
As for the WWE Championship scene, there looks to be even more going on or that will potentially be going on. Punk is in the midst of his feud with Jericho, which I've also read will, allegedly, continue for the next few months. Mark Henry is in the picture now and while he might be out of it after this Monday, who can tell? Then you've got The Rock's proclamation that he wants to be WWE Champion again someday. Then, you've got Brock Lesnar's return and all sorts of speculation as to what might be done with him. On top of all that, WWE is allegedly in heavy discussion for a WWE Championship match at WM 29 between Brock Lesnar & The Rock.
There just seems to be a little too much on the main event plates right now to feesibly squeeze Miz in. Miz hasn't been all that hot for a while now and he's certainly going to have to be built back up before fans look upon him again as a major player. It can be done of course, but it's going to take a few months at least.
I'm not sure what's ultimately going to happen with Miz but, my guess, is that he'll be sent to SD! in the WWE Draft and his career will get a good shot in the arm just like the careers of Orton, Sheamus & Daniel Bryan. I believe he'll ultimately get himself back on track as someone worth watching as a major player, but I don't see a World Championship anywhere in Miz's immediate future.
