I like the idea mentioned on Fanlore of HP sedoretu - Harry and Hermione as the Evening and Ron and Ginny as the Morning.
I mean, I just go for Harry/Ron/Hermione and Ginny/Luna/Neville, bc both those ot3s are sadly neglected and I think adding Harry to Ron/Hermione makes it a lot healthier.
Byleth/Edelgard/Hubert is a very, very good ship. And we need more of it in the world. The stuff that is there is brilliant but more! MORE!!!! Byleth/Edelgard/Dorothea is a good one too. Byleth/Edelgard/Bernadetta. Hell yeah. let edelgard have multiple lovers. let her have game as strong as her father's.
bugsnax poly stuff: i really like filbo/the journalist/beffica i also like journalist/snorpy alongside the canon snorpy/chandlo, like as in poly-V with snorpy in the middle and chandlo and the journalist on the sides wambus/triffany + floofty/triffany poly V is also very good however, the ship i am currently mostly on about is the "Polycule Expands To Cover Entire Island" ship. Fourteen person polycule. obviously theyre not all dating everyone else but Everyone Is There
my dream for cafe au fic i will eventually get to is like iscend/baru/tain hu/ulyu xe. baru is the only one here involved with iscend. hu and xe also both have other partners. shao lune was formerly part of things but due to being a toxic bitch she is just gone and not allowed near baru on threat of hu kicking her ass. when she was around though she was only involved with baru.
harryanthe like Would Not Be Healthy but like. i want to imagine like a mundane au where like. we've got a nice little v with harrow in the middle of ianthe and gideon.
I've discovered that apparently I just don't care about any shipping content for Xenoblade 3 that doesn't presume the core six to be Some Kind Of A Poly Arrangement, particularly some kind of a queerplatonic arrangement. I've only got a strongly romantic interpretation out of like two of the thirty potential pairs, the rest of it is just like "yes they're in love, yes they're family, yes they also have undeniable romantic tension with characters not within the Magically Mandated Soulmate Polycule"
