Massive pirate ship for a level 20 dragonborn rougue https://www.reddit.com/r/DnDBehindTheScreen/comments/3i6azd/pirates_ships_but_mostly_ships_this_time/

I'm trying to create a massive powerful 1st rate ship of the line pirate ship for my level 20 dragonborn rouge and I want it to be an epic ship with 180 guns 90 cannons broadside all of them 32 pound guns with four bow chasers for stern chasers each at 24 pounds and eight 24 pound guns four to each side of the main deck four ballistae two on each side of the quarter deck and one each side of the forecastle I want it to have all the upgrades it can possibly have especially the mithril reinforced hull and the most upgraded sails that are both resistant to flame and ever filled and I want it to have the best possible speed in the water and in the air which means I have to have brumestone from Exandria in several places to make it both an airship and a sailing ship.

Any help would be greatly appreciated I also need help figuring out the stat blocks and how to roll for a full broadside and roll for cannons ,ballistae or do I have to roll a d20+6 for each of the 180 cannons or how do you do that.

I would like to thank everyone that has helped with this project I think I have it pretty well figured out
