ESO engine isn't built for that kind of gameplay.
Recently I watch "Sea of Thief" gameplay and I really eager to sail my ship to the sea, fight with ghost ship, pirate and looking for valuable treasure inside Tamriel. I think the gameplay of "Sea of Thief" is quite similar with ESO , and will be great if Zos can make it happen.

It would basically be a completely different game which could be fine in theory, but would be a ton of work and a huge gamble to see if ESO and Elder Scrolls players in general even care enough about it to make it worth the investment. My guess is no.
