Jinx was really anticipated with all the she might be Vi's sister, but we will not say she is or isn't thing that Riot did for her. Giving her a music video simply helped her get more popular since the video was indeed good. No champion got an special video or comic that wasn't about the lore or skin except Jinx.

If riot releases Seth (the sand mage Morello said was shelved) and if he gets as popular as Jinx, we might see a new pre-release video for him.
