i am indeed planning to make/write more fankids! as far as bspverse goes, i just recently finished reading gaiden and i've made six bastards for kyogoku/ayatsuji/tsujimura's family, i have to finish picrewing them but once i do they'll be revealed officially with their picrews (note that ayatsuji is married to both kyogoku and tsujimura in this universe but they are not romantically involved w each other nor are they married to each other either, and their kids all share ayatsuji as a father but they don't have any kids. also ayatsuji is trans and gave birth to them so if they'd wanted a biological kid it would've had to be on purpose and they wouldn't want to anyway lmao)

i also frequently make more fankids for other verses, but the verses aren't super well developed yet and most of them have no real solid storyline, whereas bspverse is. extensive lmao. bc it was the first and the one i think abt the most. so i talk less abt those verses bc for right now theyre like. babies. meanwhile bspverse is a whole young child now

my favorite fankids are hard to properly say bc i love them all (them meaning like, the ones who contribute/will contribute to the story plotwise somehow, i do love all of them but some of them are def not my faves, not bc i hate em but bc they just kinda exist and dont do much due to being toddlers mostly lmao) so much in different ways and while i talk/think abt more of them than others that doesnt actually mean i dont love them, BUT for the other question that's a more solid answer

the kid i relate to the most who has like, solid material you can go read in "the hateful eight", is yoshiko kunikida. and yoshiko i also relate to a lot in terms of personality and some ways in experience as well, like, her childhood is still way nicer in terms of how her parents treat her than mine was (hashtag abused child check) and she's def not abused by kunikida and katai, but she does have some of my disorders (OSDD, chronic fatigue syndrome with hypersomnia, ADHD, autism) and struggles with (later on) her physical appearance in ways similar to me. we're also built similarly body type wise and she, unlike most of her peers, is physically incapable of reaching the same levels of strength and activity as they are, which is relatable to me and always has been (i've never been able to do exercise the way most kids were, and now i can't do it at all due to pushing myself to do it as a kid bc everyone thought i was just lazy lmao. luckily that didn't happen to yoshiko but yknow, similar =/= the same)
