Island themes?

Idk what to theme my island as and I can't think of any I like 💔 I wanna keep my villagers too (Judy, sherb, marina, maple, cookie, Raymond, Gayle, étoile, merengue, and stitches but I'm okay with kicking him out) so that might make it harder. Ik not everyone does themes but I feel like they motivate me to play more instead of abandoning it for months, and I wanna keep playing for the 3.0 update in January. I've already done kidcore, farmcore, and fairycore so...I probably don't wanna do those again, any ideas?
