Revisiting existing races

Will we ever see new champions of existing races (not talking human, yordle, voidborn). Will we get more Trolls or another Darkin? You have champions that are interesting and would be a shame if they alone represent their race, I would love to see a different troll. (I understand that it is hard to create interent new champs for races like the Ursine due to volibear's skins would make it not har to create an ursine that looks different enough from him asside from being just a mage Volibear)
