I've been wondering after the collaboration with Pirates of The Caribbean, but what if Sea of Thieves were able to have some collaboration with One Piece?
The collaboration doesn't have to be a story-driven update or something, maybe One Piece Ship skins of Thousand Sunny and Luffy's Crew clothing and weapons with some events that makes player able to buy some unique skins, just like several events before
For example; Ship Skins for One Piece "Marines" can be obtained by doing Merchants Events, Thousand Sunny ship skin can be obtained by doing Reaper Events, Whitebeard's Ship skin "MobyDick" (That's the name, not an insult) for Pirate Legends / Athena Events since Whitebeard basically are One Piece Legends, and some more, just like rewards you can obtain during "Festival of Giving" style events
While doing those events, we can also get some clothing skins as well from season rewards. for example; we can get Monkey D Luffy clothing set with his Straw Hats, or Zoro's Three-Swords skins, or maybe Captain Kidd "Metal Arm" Hook and many more
Or maybe the ship skins can be purchased on Pirate emporium, as long it's not like a Story-Driven Update that forced The Developers to think hard about the story
I think it's gonna be pretty neat to have those collaboration so people that came with Anime Background can also enjoy roleplaying become the strawhats crew and stuff
If this idea was taken, maybe also add Bink's Sake song on the shanty as well, that's the icon of One Piece music
