Not sure if you mean if it was made this way in 2013, but I'll assume so.
While some people are fans of traditional animation for various reasons (preference, nostalgia, etc.), I don't think you'd get the same level of fervor for the film if traditional animation was used. For one, you would not have the highly detailed snow and ice effects. For another, the character styles would be vastly different, and thus the tone of the film. But just those two things would lead to a very different film, and these days such traditionally animated films do not gross nearly as much in the box office, as they are perceived differently and have to be marketed differently (see The Princess and the Frog, for example). Similarly, such a film would not be able to enter certain markets, such a China, and even if it somehow squeezed in, all likelihood it will not make a tenth of the box office it did in those markets, as there is little to no preference or nostalgia for traditional animation; for markets that are mostly just being able to receive such products or for markets that are just opening up, traditional animation is something perceived low quality and cheap, whereas computer generated and enhanced animation is perceived as an affordable luxury and immersive. In all, it would have been able to break even in the production sense of the phrase (The Princess and the Frog did not, since a rough rule of thumb is to make three times the budget on the box office for breaking even), but it would not have been the hit it was, not have made as much of a cultural influence, and it would have probably been eclipsed by Despicable Me 2.
Minions, yuck.
