At this time, I'd have to say no. Ryback has absolutely zero momentum right now and, to be perfectly honest, I'm a little surprised that Ryback hasn't already been WWE Champion. I think a major factor in that is due to the timing of Ryback's push in the latter months of 2012. CM Punk was the top heel in wrestling during that time, had been WWE Champion for almost a year, was doing a great job as champion and was scheduled to face The Rock for the title at the Royal Rumble. Frankly, Punk vs. Rock was going to be more of a draw than Ryback vs. Rock. Had it not been for the fact that WWE wanted The Rock as champion heading into WrestleMania, I think there's a good chance that Vince would have really jacked Ryback's push and made him champion.
I think it was a smart move by WWE. During that time, there was a surprising number of people on the forums who believed that WWE should put the title on Ryback despite the fact that he hadn't really been tested. He was the latest thing and was in a feud against the top heel in the business at the time, a feud that was getting a strong response from fans. Afterward, he found himself in a brief feud with Mark Henry, which he lost, then found himself feuding for the title with John Cena. All in all, I enjoyed Ryback's matches with John Cena and I thought he honestly came a long way on the mic. However, WWE didn't put the title on him and I have to imagine that it's because that they simply weren't all that impressed with his progress. It's still possible Ryback could be WWE Champion someday, and I can almost certainly still see him being World Heavyweight Champion at some point.
Ryback has a fantastic look and presence with very believable intensity that goes right along with that great look. In my eyes, Ryback is a pretty damn good powerhouse wrestler. Even though he still gets the "Goldberg" chants, in my eyes, he's FAR better than Goldberg ever was. Five years ago, Ryback would have been champion, I've no doubt about that. It's kind of refreshing, however, to see WWE not putting the title on Ryback. I think it reflects a definite change in booking decisions that wasn't there 5 years ago, a style that would have pushed Ryback as a younger version of either Goldberg or Batista even though there are a lot of much better overall pro wrestlers on the roster.
Ryback's only 31 years old, he's still a young man and could have a bright future. He could be ready someday, but it's not now. Right now though, in my eyes, there are too many other wrestlers who are more talented I'd rather see get pushed.
