i've seen figure skater sanji and hockey player zoro before. idk if its been explored but i'd love to put it out there:

hockey player sanji (specifically goalie bc he desperately wants to avoid being checked) and then pairs skater zoro.

pairs skater zoro's long time partner has been nami. though many people ship them together a Lot, they just know each other super well. Well enough to try dating and both of them realized they don't swing that way. in fact, it makes them a really good team. they fought long and hard to claim top spots in competitions because they portray a chemistry that's separate from the rest. plus zoro can carry nami like she weighs fucking nothing. so their lifts are so much more dynamic. they even have a whole next to impossible combination that they're trying to get the ISU to name after them officially.

sanji plays for the East Blue Straw Hats in the Grand Line Hockey League – a formidable rookie group that took down lots of big names in the preseason. they want to make it all the way to the postseason playoff finals but always seem to fall short. but theyre so determined. they reignited a lot of old sparks that were no longer there for old fans and brought in new and curious fans. sanji is the starter goalie and a damn good one at that. it makes sense bc goalies are often doing splits on the ice just to make a save. he's perfected the technique that utilizes just his legs to make saves that make the crowd go fuckin insane.

we have the usual "i booked the rink to practice before you did" trope but a little more spice. in actuality, sanji loves watching pairs skating competitions. his favorite pair rn is franky and robin (mostly for robin). and he adamantly does not want to admit to anyone that he watches zoro and nami's routines much more frequently. (and if anyone asks, he always says its bc of nami. its never just bc of nami.) and zoro's besties with luffy so he always watches their matches even if he barely understands the rules. and he definitely does not stare at a certain blond starter goalie most of the match thats fucking ridiculous

one day zoro and sanji are invited to do one of those comparison videos between hockey players and figure skaters. both get to laugh at the other even Attempting to do their sport. zoro frankly looks ridiculous in all of sanji's usual goalie get-up. and sanji couldn't land an euler to save his life. the video producer suggests they try a simple pairs skating routine. sanji is like "oh i couldn't do that–hEY WHAT THE FUCK MOSSHEAD PUT ME DOWN" because zoro lifted sanji and had him sat on his shoulder like it was normal.

zoro smirks, "you might be lighter than nami, actually. wanna be my new partner?"

sanji knees him in the stomach before skating away while blushing so hard he could melt the ice beneath him.
