Will there ever be another transforming champ like Nidalee and Elise?

Where your R gives you a new form with different abilities? I'm not talking about transformations like Kayn or Elementalist Lux where you charge the transformation and then that's what you get for the game, one where you go back and forth like the aforementioned champions.

I personally really like that mechanic and concept, and with Runeterra being such a magical place it would be awesome to see more champions that can do that.
