In some web surfing today I discovered an Age of Sail warship that never made it past the planning and scale model stage. HMS Duke of Kent if built would have far out gunned the Santisima Trinidad at 170 cannons. Here's a link to some additional information.

This ship certainly would make an interesting kit bash, but from the article I think the HMS Caledonia would be a better candidate, although I cannot find Caledonia's class listed on Three Decks?
