What about particle recolors?

So with the chroma packs going live there has been a lot of talk about skin recolors and all those kind of things and how a lot of the 750 RP skins feel underwhelming because they have interesting new model or outfits but the same particle effects which make the skin seem less 'wow' or unique.

What about simple particle recolors?

Lets take kennen for an example (Because I would love this on him). All his skills have pretty cool lightning visuals on them (I dont know if they should be called 'particles' technically). But non of his skins really do anything special with those. Mostly because that his skins are old before doing new particles was a thing riot did a lot.

So what if his deadly kennen skin had red color lightning bolts/sparks/thingies (how do you call them?), like when he does his W all the sparks that fly are all red and when he ults the ring of lightning would be red colored (or red glow i dont know how exactly the graphics are made up).

Those kind of changes would be lighter than completely re-doing and recreating new cooler particles for a skin but instead you just recolor the textures that are used for the current particles. Wouldn't that be something that could be done easier without upping the price of a skin to 1350 right away?

ideas?
