I see no real reason why they should be tag team champions. Sure the pairing looks to be something that could work, but do we really want it to work? A lot of people have been all up over the idea of Zack Ryder getting a push, but where would he honestly benefit mostly from it, the same goes for Mason Ryan, where would he benefit mostly from it? Carrying a dead tag team division, or being the United States champion, that both of them have been hinting some sort of possibility of, with their clashes with Dolph Ziggler in the past months time.
Besides, with Airboom being the current champions, there would be a need for a switch of the titles over to Dolph and Jack Swagger if the title change would ever make any sense, because why would WWE take the belts off a popular tag team, by letting a less popular on the rise tag team take the belts from them? Exactly, no sense to it. Top that off with the fact that if there was to be any momentum going around it, Jack and Dolph would have to hold the belts for a fair period of time, for Zack and Mason to finally knock them off the pedestal.
I'm not against the idea of the pairing, but it's obvious that both of them will benefit more from a singles career, and to be pushed as singles competitors. Besides, it has only been a few times that Zack and Mason Ryan have been on the same segment, so there's hardly any hints of them being tag team partners in the nearest future. Only possibly thing there could be hinted, is Dolph Ziggler getting thrown into another multi-man title defense (A Fatal 4 Way maybe? you tell me..).
So while it could work, if WWE was to go that way, I don't see any reason why they should, or any hints that they are any time soon.
