What would you guys think of a Star Guardian Kayn?

I play a lot of Kayn and more often then not, think about what types of skins he could get. While it probably will never happen, I'd recently thought of what a Star Guardian version would look like. It would actually be pretty interesting, as I was thinking of Kayn having the potential to join the Star Guardians, but being the Edgelord he is denies it. With some leaks (Which are probably fake) supporting the idea of an Anti-Star Guardian skin line, we could make Rhaast a weapon from the villan he was, or even some powerful artifact that one of the void beings had brought to the city.

Kayn could find the Scythe, and unsure about what it is, grab hold of it, combining him and Rhaast. It could then go something along the lines of Kayn having to join the Star Guardians, so that they can help him control the Scythe, and keep Rhaast from consuming him and being reborn.

The color scheme could go with a Yellow and Purple, yellow for Kayn and Purple for Rhaast.

While this concept has been talked about a little bit, I'm honestly still curious what other people think of this idea.
