How about Feline club kwami swap? I mean, for some reason they had to swap their miraculous. And by the way, I love the feline club idea, It will be an au like Rabbit Hole?
Lila and Alix would not do that great with Prowl. Lila would have an issue with being invisible and that would hinder her, she'd be kinda pissed that she only has one power. Alix would do better than Lila, she still might have some issues with self-control.
Ivan would struggle with Brilliance but would be happy to have a Cure. Alix would have some better control of Brilliance, as it's better to perceive than Cataclysm and her precision is pretty good so she'd do better with staying further away from the fight and doing stuff from there. She probably wouldn't like it tho
Lila wouldn't do bad with Cataclysm but would prefer Brilliance since it's more attention-catching. Ivan would also do better with Cataclysm, Brilliance is just more scary to him.
As for the kwamis, Lila would find Roaar and Plagg a bit annoying. She'd get along with Roaar quicker than with Plagg.
Alix wouldn't mind Luxx but she'd think that he's a bit bland. She'd really like his nonchalantness with the miraculous stuff and how much he tells her (she'd be kinda concerned/suspicious at first tho). Roaar would love Alix, thought Alix would find her a little annoying, and thinks that she could tone it down a bit or be less,,, childish.
Ivan and Luxx? Great, absolutely chill, Luxx would encourage Ivan to be more free and stand up for himself. Plagg would keep his distance at first (just like with all of his holders) but would warm up pretty quickly, maybe he'd think that Ivan is a bit boring and could spice his life up a little.
No, it was just an art request and ask. I wouldn't have thought of this thing if no one asked.
