Variant Summoner Spells

So what if Riot implemented this idea of summoner spells having different variants, kind of like how smite has different workings depending on the item (so we know it's possible as well). So what if flash could be used as it currently is, but the variant allowed you to flash farther if not in combat? Or what if Ghost had a variant for a longer ramp up, but faster speeds. How about a teleport where you could teleport to a champion like Shen but it had a long ass cd. Just some thoughts to consider about summoner spells. Please notice RIOT!!!!!!!!!
