The problem is the game takes place more than 45 years after the end of the Civil War so it wouldn't be in character (not that zombies are in character either, but that's another story). I think the game has been so critically and commercially successful, though, that it could pave the way for similar open world Old West games that might take place closer to the Civil War era. Your idea of the cavalry sabre could work, though, especially since there are American and Mexican army in the game that might have had them attached to their rifles.
