Idea about Kayle and Morgana Rework Lore

So, I had a shower thought the other day. Obviously, Riot is planning on delving deeper into the lore of the Darkin, with 3 of 5 known existing Darkin already within the games. There is a popular theory among the fanbase that the last two remaining Darkin are actually Kayle and Morgana, what with their reworks (lore and gameplay) due sometime soon.

This is just a suggestion of mine. What if they rework Morgana to be a part of the Darkin (maybe the Darkin of Pain), and change her weapons to that of chains/whips - seeing as most of her kit as of now revolves around some sort of binding or shackling. And what if they also rework Kayle to be what the Darkin were before. Basically incorrupt Darkin? Maybe called Archen or Archan - from Archangel, to go with the Angel-Devil thematic dichotomy the two sisters have. Plus, it's cool and sounds kinda like Darkin. Maybe have her be the Archan/Archen of Justice.

Lore-Wise: Maybe there was no Angel-Devil celestial war to begin with, and the story of the Darkin is one of rebellion instead. I noticed that some of the Darkin's "aspect" are seen in a bad light, but can actually have some positive sides to them. Just as Aatrox is the Darkin of War, he could also be the "aspect" of Progress, or how Varus can be Darkin of Vengeance, but also of Atonement. Rhaast is to Death and to Balance, etc. Maybe its this realization that made some of the Archan/Archen rebel and become the Darkin. Some kind of Old War happened, and the last remaining 5 (who may or may not have been spared thanks to Kayle) walk the Earth, or are imprisoned in some way. [Not good with lore so leaving this story as is] The final conclusion is that Kayle may have doled out Justice, but at the cost of being the last of the Archan/Archen, and she has to live with it. Meanwhile, Morgana has been gathering the other 4 Darkin, freeing them of their "Bindings", and giving them permission to inflict pain. Brings a whole new meaning to Morgana's quote "We'll bring them Pain."
