Pipe Dream

Ship’s forces often raided ashore and even captured forts and Islands. Morgan’s Sack of Panama was an naval operation.

The proximity of ships should also mean that Land Armies are tied up incase of raids and attempted capture of settlements. Why do you think that Marine compliments were a part of almost every ship in every navy of the time?

The first American Amphibious landing took place during the Revolutionary war. On March 3, 1776 the fleet's Marines and a number of seamen under Marine Captain Nicholas splashed ashore about two miles east of Fort Montagu, one of the Bahama Island's two forts, which they captured in a battle as "bemused as it was bloodless." After resting the night in their prize, the invasion force completed the job the next morning by taking Fort Nassau, securing the town, and arresting the British governor. By March 16, the island's military stores, with the exception of the gunpowder, were loaded and secured. The Marines and seamen who took part in the landing were then embarked, as was the governor and two of the island's key officials. The following morning the signal was given to weigh anchor, and the force returned to America.

Naval Bombardment would be great but I fear it is beyond the capabilities of the game engine.

No it wasn't. Ships dropped Henry Morgan off safely away from Chagre and picked him and his spoils up again a few months later. That's about the extent of the naval component. Morgan's fleet was located in the wrong ocean(!) for it to have been a naval operation.

Uhm... To have a trained body of fighting men in a boarding action? To enforce shipboard discipline? Did they at times carry out raids? Certainly. Did they participate in amphibious battles? Hardly ever. To insinuate that the latter is why navies used marines is mere truthiness.

So, even in this example you give there was no opposed landing nor, judging from the text, direct naval support. As such it's a textbook example of how such actions were typically fought. Therefore already within what Total War can model, correct?
Not that I'm saying it never happened that marines and seamen carried out opposed landings, but as a whole, it was a method not used enough to be worth any serious programming time.
We're talking flaming pigs and screeching women here, let there be no doubt about it.
