I know I mentioned it before but the more I think about, Danna Paola really is overall the strongest choice in terms of the balancing act of talent, recognition (but not superstardom), age range/looks (she's 29, short, and gorgeous), and ethnic background.
Let's put it this way-not that social media is an indicator of everything, but Ariana DeBose has 700K followers on Instagram. Danna has just under 33 MILLION followers on Instagram. That said, that may make her too famous and uninterested in taking so much time off to move to London/devote herself to such a strenuous process. She might not even be remotely interested since she's already doing so well in the (very large) Spanish speaking market-and Ariana DeBose may be all but a done deal. Fun to speculate, though.
