I would personally love this!
Ok, I know this is going to sound like Disney making more money on something that is a hit, but I would love this. I think that they should build a full size replica of The Black Pearl and put in the lake they have in Magic Kingdom. I know that its not that close to Pirates of The Caribbean, but that would be the only sensible place they would have it. I would love to walk around the ship and exploring. I wouldn't make it boring like the Swiss Family Robinson Treehouse, but I would put a lot into it. For example, I would have a cabinet that would read " Don't open: Ye Be Warned... savvy?" And have the cursed monkey pop out and scare the tourists, that would be great!
