Xayah/Rakan 'Star-Crossed Lovers' skin concept (no art)

While I was talking with some friends about the new skins Riot has released, the idea of Xayah/Rakan perhaps having skins that are entirely different came up. I pitched the idea of Dark Star Xayah and Star Guardian Rakan (or vice versa), and then the phrase 'star-crossed lovers' came to mind, and it just seemed too good to keep to myself.

Others have probably thought this up before, but I wanted to plant the seed if anybody else likes the idea.
