That being said. I’d say that moving the timeline all the way up to the American Revolution does pose the issue on the current game machanic of swords playing a major role in combat. By this time peroid firearms were more common place and edged weapons were approching the twilight of their usefullness in “modern” combat.
Not to mention that it was difficult for regular citizens in the colonies to openly carry any arms. (The Second Amendment was not based just on firearms)

The Tomahawk is a great addition, and the AC series commonly “steals” from the near future so I’d expect to see some type of cartridge/cap based ammo to facilitate faster reloading.
