Theme songs for all champions

There are a lot of champions who were released before the time of theme songs. A lot have recieved VGUs together with login themes and thats great, but some updated champions have not gotten a theme, which is too bad because a theme really is a great way to portray the champion and gives them more depth and character.

Champions like , , , just to name a few have gotten some kind of polish/rework but still lack a theme.

Would it be possible for Riot to, similar to the VGUs, create themes for those champions who already had a modern VGU but not a theme song? Im certain im not the only one who wants to know Riots musical vision for classical champions like and the rest.
