Will the current champions feel out of place on the new map?

The new Summoners Rift update looks amazing right!?!? But it is a little more cartoonish now and i feel like some champions would just feel out of place and not really be apart of the map like Sion or Nautilus. The only champs that I see that really fit in are the champions who have gotten visual reworks like Twitch and Karthus. I am almost sure Riot knows about this so are you guys gonna do visual reworks on some champions so they can really fit in to the new Summoners Rift?
