Updating Legacy and Older Legendary Skins to Current "Legendary" Standards?

Will legacy legendary skins ever be updated, or are there any plans for updates on them in the future? I'm talking visual updates to make them legendary by current standards. Some skins can be misleading, such as Gentleman Cho'Gath, being a legendary you expect new particles and effects, a voice-over, & new textures and that is not what you get. Some parts are great, but something to really make them legendary would be nice, (I.E. new effects). I mean, some of the more current 1350RP skins are better than these listed, such as Dragonwing Corki, Pool Party Mundo and even Soulstealer Vladimir, in my opinion. Of course they have nostalgic value for being legacy or some of the first skins, updates to current standards should be included in Visual Updates at least; like Annie's VGU where they ignored Annie in Wonderland. I sure hope with the upcoming Galio update they retouch Gatekeeper Galio. Just my two cents on the topic. I own all legendary skins except Annie in Wonderland and Zombie Brand (planning on getting next October), I just feel like some of them could use some retouching or adding to them. I understand there's a lot that's changed and you have the right to not use them or just not get them. That's not my point, my point is that by current standards, as per Riot, these skins are not Legendary aside from nostalgic value, and as such should be updated to be what they were intended. Most already have voice-overs, and extensive re-textures, so the main addition would be for the visual effects. Thanks for reading and hope you agree with what I'm trying to say.

These skins seem kind of lack-luster for being legendary:
