I don't know if this has been thought of before, but I had a random idea for a new Cassiopeia skin: one based off of her real life constellation, and it can be called something like "Celestial Cassiopeia". Let me know what you guys think :)
I think most of the new particles for that would be put into her Miasma, in which instead of being poisonous gas it could be like a little glimpse into space or something. The rest of her particles would just be recolored to blue or purple. At best she'd get some sort of animation, like starts or something, on her E or basic attacks.
Though maybe her tail could be like 
and just kind of reflect space. That would be cool.
