hello! i have a kaeya and/or childe (lackluster) that i can offer for the scenarios you listed out. i haven't really gotten to write out a reconciliation arc with kaeya and diluc to its fullest so it would be a lot of fun to unravel that, no matter how long it takes. but also! exploring the khaenri'ah/abyss connections with childe and kaeya would be a lot of fun too... so i am up for either one depending on what flavour you're more interested in writing out. c:
