If you had to make a dlc for civ rev 1 or 2? What civ/unit/tech/scenario and map would you add?

When making the Google doc for civ rev 3. I'd imagine it as an expansion pack for rev 2. But if I had to make it a dlc I would add:

Civ: Poland Winged hussar, Vistula legion and home army

Start the game with all units having a plus 1 defense bonus

AEB: granary is built for free

Middle age: all cavalry have +2 movement

Industrial era: Vistula legion (riflemen) gain extra combat strength

Modern: gain. Production bonus of communism without its downside or needing to adopt

Tech: rifling (move rifleman there)

Unit: musketeer (to fill that gap between pike and rifle)

Scenario: Napoleonic war Fixed Europe map with Napoleonic france, England, Germany, Russia and Poland

Maps: Europe, Africa and all of asia
