I absolutely love those ships!
I love that you have used that colour for the Swedish ships instead of the otherwise so common okra/beige/yellow line. It was common for Swedes to just use varnish.
Me personally would have chosen to have a 74 or two and then 60-64 gun ships (of the
Wasa-class) for the rest of the ships of the line. Sweden preferred ships that could navigate the archipelago and the 64 gun ships built by Chapman was a great stable gun platform, unusually heavily armed, and with a shallow draft.
