What if a skelly ship could obtain and stack, all the human loot of ships they get sunk, that way when you see a skelly ship you'll never know what loot has inside.
What if when in land and you get slayed by a skelly they stole a random loot from your inventory, that way sometimes you can kill a skelly that could give you a useful item when you least expect it. Of course you can always get your revenge and recover the item, but sometimes that will not happen and if the process repeats then items stacks.
This will give you a little more rewarding experience by just exploring and who knows, maybe that skelly galleon you always avoid, has taken out lots of human ships and it has really cool loot(even vault keys and manifests), also imagine getting into an island start fighting some skelly that drops 5 firebombs or 10 cannon balls, it would be pretty cool.
Having that by pure luck or when you really don't expect it, i think it could really enhance your gameplay experience considering this will not happen often since skelly's are easy to kill in general.
