No it really wouldn't at all.
Notice the emphasis on being recently prominent in Pokemon-related stuff? Yeah, Zoroark isn't curently the character in the spotlight and has nothing going for her. Mewtwo is the poster boy for Gen 6 and is in that movie with Genesect, Lucario also has a Mega Evolution and to boot has a major role in X and Y, Pokemon Master and his Pokemons also has stuff going for them promotion-wise and Gen 1 starters were pretty prominent in X and Y, being default Pokemons that could be chosen. Even Jigglypuff has more going for her recently than Zoroark.
Zoroark is very unlikely to get in currently over Jigglypuff, Pokemon Master and especially Mewtwo, the single most requested character world wide. Zoroark is a potential newcomer with just too many things going against it. Even if they wanted a newcomer, they would more likely to go with someone like Sylveon, who has the one thing Zoroark has and more.
Keep in mind that Sakurai said that he won't be cutting characters out of the way and it is even less likely that Zoroark will get in over the established veterans.
Ike? The difference between Ike and Zoroark is that Ike is easily one of the most important characters in FE due to being one of the only characters to star in more than one game, and even in Awakening he is still more "relevant" than Zoroark was right now due to him having a side chapter
dedicated to his legacy.
In short, why Zoroark at all in a prediction roster?
