Morgana and Kayle Have Huge Thematic Potential
I've always thought that Kayle has a lot of thematic potential, even if her current theme is as cliched as a battle angel. Recently, I learned that Kayle is on the list for a VGU. I kept thinking about what the could come up with, and realized that both Kayle and Morgana could become really cool champions with very tiny changes, so I decided to write about those changes on here and see what you all think.
For Kayle, I think lore-wise the best thing to do is to integrate her into the Solari. Her color palette and almost all of her skills are symbolic of the sun itself, so this would be very easy. Her ult looks like she becomes the sun itself! Visually, not much has to change (except maybe make her armor look a bit better, more specifically: her pauldrons.) except for her wings. I think she shouldn't have actual wings with feathers, but rather ethereal looking wings with a fiery theme to them.

As for her skills, I don't see the need for her passive, w, e (especially not e), or R to change. Her Q, though, could become about 20% cooler.
Q - Reckoning: Kayle summons a fire ball that falls from the sky and explodes at target location (imagine a veigar W but bright and covered in fire) dealing damage and slowing down everything affected by the blast.
Notice how it's similar to old q, but is now a skillshot that is somewhat difficult to land and it's now AoE to compensate. In this way, Kayle could try and land that Q on multiple opponents, making them all susceptible to her e at the same time, which would be a just reward for landing a perfect skill shot.
Although I don't want E to change functionally, I feel that more could be added to its visuals to fit the new theme. This is what I had in mind: when Kayle activates her E her entire blade should turn a very bright and light orange (almost white, as if the sword was getting really hot) and it should look like the blade is subtly bending like waves, as if the sword was alive. When she swings her blade with e activated it should extend itself and look like she's whipping her opponent, with flames splashing all over and around the target from the sheer intensity of the heat coming from the blade.
That's about all I have for kayle. As for Morgana, since Kayle is now a Solari I wouldn't want morgana to become a "lunari," that wouldn't fit her theme and would steal Diana's identity. Instead, Morgana should be a former Solari who became corrupted by the void. Yes, you read correctly, the void. Her current color palette meets the standard. Her wings already look like some cancerous mutation protruding from her back as the void tried to turn her into an alien-like form, and her "black shield" skill could be symbolic that she and kayle once shared the same power (Kayle's ult), but even that became corrupted by the void. Kassadin's passive also protects from magic damage, which is another hint that having void powers gives you protection from magic damage.
Lore-wise you could do for Morgana what Demons' Souls did for Maiden Astrea. Morgana could've been the opposite of Kayle in the sense that she did not want to bring justice by inflicting pain on the unjust, but by healing and easing pain on the victims of the unjust. She doesn't have to hate Kayle eiher, the two could've been very close at some point, but Morgana had to accept the corrupting powers of the void from some unknown source in order to save someone (maybe even Kayle herself) or a group of people (maybe some wrongfully convicted group of people that are now being targeted by the Solari). The two sisters would now be two sides of the same coin.
This is all I have. The overall changes are small. Nothing big and almost everything stays the same. But, with just enough new detail to make these two champions into full-time badasses of League.
Although English is not my first language, I accept any criticism to my writing skills.
