Riot, how will traditional skin splashes be done in the rework splash updates?

I know you guys no longer plan to do anymore traditional skins and that it seems like you guys don't really like to talk about them, but this seems rather important.

With reworked champions getting updated skin splashes in the future, I'm just wondering how the traditional splashes will be touched.

With Trundle and Sejuani, it's not that much of a problem but with Karma her traditional skin is rather different compared to the splash art.

Will you be going over traditional splashes at all?

Will they just receive little tweaks?
