Player forts, Royal Navy, Clans, Naval Forts.

What if the players of Sea of Thieves didn't just have skeleton forts and skeleton ships to worry about? What if there was a bigger part of the map unlocked and theres nothing but Royal Navel Forts and while skeleton ships explore the seas, there could also be a fleet of the Royal Navy that you could also fight. This fleet could consist of 2 sloops, 2 brigs, and 1 galleon. Add like a new tier of Gold Holders chest called The Queens treasure (Or the kings). Add new Merchant Alliance crates like crates of wheat, crates of exotic foods,ect..
If the map could be expanded again to add a bunch of islands that players cou lkmd inhabit, claim for their own and build a fortress of their of design. I would say have players buy the upgrades for these fortresses but have a folder or some type of box that you can open, and save your design so if you were to join a different server you could just go to this box at any of these islands and upload their design. Players could add turret towers (or defense towers) with mpc pirates to help you defend your fort. Within the fort you can build your stronghold to store your treasure so you could hit an outpost all at once with your great loot. Other players cant attack your fort if you're not currently there.
Just like how on the docks we can customize our ship to look amazing when we set sail to become legends, you could do this two different ways. 1.) When you spawn in could walk over to the dock, customize your ship, then buy the upgrades. 2.) You could do merchant missions and when you find the goods you could either turn them in for loads if cash and EXP, or take to the dock women (where customizes your ship) and give it to her and get the upgrade free. The upgrades could be stronger hull, stronger cannons, stronger sails. These upgrades would be permanent, you would just have equip them when you spawn. Also what should be added to came is another vendor on the dock that if let's say spend 1000 gold on, they will fill 25% of your stock per barrel, (cannonballs, wood, bananas). It makes sense to only be 25% because if they got to fill the barrels 100% it would be unfair to those players who cant afford that much supplies, eventually someone would run out wood and one ship would be full on it. Just isn't really fair.
Clans could be added into the game to where you become a pirate lord and you have people join your clan, it would be the same as alliances but permanent. Instead of a whitetags above their names it could be like blue. You could make the name of your clan and you could design your own flag online and upload it to the game. You could set other players ranks in the clan, rank 1 being the lower levels, level 5 being your closest allies. As well the get 50% of what you sell. (As long as in same session) Another thing that could be cool is if there were clan wars. Where its 5 ships v. 5 ships. The ships would be galleons too, and the session matching could pair you up against a clan similar to your size. No bigger or smaller. Same size Clans vs each other.
Those are just my ideas, hope you all enjoy them.
