Hmm, Super Mario Bros was a much better fit for Illumination honestly. That movie was quite a bit better than anticipated, but also the series just flows into Illumination's brand pretty well. Zelda feels a bit more aged up, if this was to happen I'd have hoped for a different studio but hey, we'll see what happens with it.
I still think a BotW show in the style of The Last Airbender would be the best use of the property for movie/television. An amnesiac and more talkative Link goes across Hyrule with some friends learning about the past of the Calamity and his destiny, helping out Hyruleans in need, and training to defeat Ganon by the series finale. That'd be sick.
