Here is a list of crackships/rarepairs and the dynamic in which I think they'd work in! I challenged myself by only making up ships I've never (or almost never) seen before >:)
Disclaimer: These can be seen as platonic or romantic!
Kitajima: Ushijima x Kita, autism, stoic pair, they'd have a very peaceful lifestyle together and take great care of their help, FARMER BFS!
Fukuten: Fukunaga x Tendou: Prankster friends, love being unserious and cooking!! Fukunaga loves Tendou's desserts and Tendou likes Fukunaga's savoury meals, also Tendou helps Fukunaga brainstorm for his job as a comedian and Fukunaga gives Tendou ideas for desserts?
Kitasaku (I might've seen something for this pair before?): Kita x Sakusa: Aka Atsumu's gay panic, they both like their life in order and are cleanly! They have a deep respect for one another I'd say
Aonaga: Aone x Fukunaga: I don't know HOW this came to mind, but I feel like they both would thrive in a domestic setting, i.e. they'd be in a knitting club together or bake cookies for charity. Very cute stuff
Koutarai: Bokuto x Hoshiumi: White/grey haired bird guys,, athletic to a point where you genuinely wonder how the fuck they're doing it and it always makes for a fun party trick lol (They can both do flips and whatnot), also them exchanging clothes would be very funny (seeing as Bokuto is an XL and Hoshiumi is most likely a Medium)
Sunasaku (preeetty sure I've seen this somewhere too but still): Suna x Sakusa: Flexibility freaks, they help each other through the joint/muscle pain, will talk ABSOLUTE shit behind someone's back if they don't like them lol, (also a little hc: gender non conforming, both of them (even though the don't bother with labels))
Atsugami: Hirugami x Atsumu: The hunger for perfection got both of them fucked up for a while, cocky bastards that like winding eachother up, they can get REAL scary when determined (For an added bonus, add Oikawa to this equation)
Atsuken: chronically online duo, Atsumu is deeply invested but his posts flop all the time and Kenma isn't even too interested but gets hit posts every other day lol, ALSO they bleach each others' hair maybe?? (I think both of them look great with brown hair that might just be me though)
Asaten: Tendou x Asahi, Paris bfs, they like going out for coffees together and Tendou uses delivering chocolates as an excuse to 'annoy' Asahi at work
Tanaiwa: Tanaka x Iwaizumi: GYM BROS,, need I say more
Shiragami: Shirabu x Hirugami: exhausted med students, they're both kinda bitchy and gossip sometimes
Kozudashi: Kenma x Yamaguchi: They bond over knowledge of technology, both of them have anxiety and like to spend quality time together (sometimes just in mutual silence)
Ennosaku: Ennoshita x Sakusa: Joint pains and joint relief? I feel like Sakusa would give Ennoshita good advice on how to relieve anxiety while he's battling med school lol
