Can we expect to see a Dr Mundo, Kennen, Ryze and Nunu Visual Update in Season 6?

I made a post about Dr Mundo a few weeks ago needing a visual update and this is sort of bumping that up but also made me realise that these 4 Champions are in DESPERATE need of one too, they do not mesh visually with the map any more at all.

Ryze only got a slight particle effect and shading update from his rework and was mentioned from the art team that they are working up a VU for him sometime soon but has not been followed up since it was mentioned. Can any Rioter's make a response if at least the VU teams have discussed these characters to be visually updated?

Update: Thank you for all the comments on this post, I agree limiting to just 4 champions isn't enough but I thought pretty hard on what champions just really stick out as ugly but then from the comments I have realised there's many worthy mentions for example Pantheon is also pretty grim (those toes man).

In my opinion Dr Mundo is the worst looking one out of all of them if I really had to choose one who's just wanting some visual attention ASAP. Things to point out: Smaller than most tanks like Nautilus and Sion. Has 3 toes on each foot O_o. His eyes are cartoon googly eyes. Old particle FX (his ult needs some work as it's just spinning rings that don't really make clear that he's regenerating unnoticeable if it wasn't for the sound effect) and finally very clunky turn animations.

Thanks everyone once again :)

Just to clarify: Ryze did NOT get a Visual Update he got a texture rebalance and a added graphics effect on his tattoo's that glow when his passive is used. He still has the same model, textures, voice lines and animations.
