Favourite theory I heard was that the One Piece refers to all of the oceans being joined by destroying the strip of land in the centre of the cross shaped continent. They foreshadow it by having every character dream about the different types of fish all co-habiting in the same ocean.
The destruction/removal of the Red Line which is the Mountainois ridges that go North to South round the world. But you would still have the Grand (East to West) that would prevent all 4 oceans from meeting.

Yes that’s what I’m talking about.
