Grand Pianist Sona

OK I know that DJ Sona just came out and she already has plenty of skins, but still. Why isn't this a thing?? It almost makes too much sense to me. Simply replace the strings on the instrument for keys, add a purple or black dress (any color other than her present skins really), and replace the sound effects that happen when you use an ability from harp strings to piano keys. Keep the shape of the instrument, but give it a sleek black texture similar to most grand pianos. Let her ponytails flow down her back and there you go! Grand Pianist Sona! So again with my question: why isn't this a thing?

Please let me know if I'm just crazy or if people haven't thought of it because they are two different instruments. (and yes I know arcade Sona has some keys on her board.)
