Kayle + Morgana Rework

So I'm guessing that the release of Xayah and Rakan is Riot's experimenting with the idea of Champion ability interactions and how two champions can be released at the same time and have more of a conversation with their voicelines, an experiment to prepare for and 's rework?

I'm guessing they're not going to have any ability interactions, but I can't wait to see how they interact with each other through their voicelines!!!
