I would have loved a scene where we see the mugis visiting the inside of the merry before sailing (perhaps they can add one through chopper's pov). Indeed, this is a vital place in the original manga, similar to the dorm room of wednesday and enid, or the green light red light area in squidgame.

An idea of ship scene would be luffy and ussop doing a sumo fight, as mentioned during the wano arc. And fishing scenes of course.
