Not to mention that we'd still need eras for Templars, Assassins and Instruments and if we're using Assassin insignias for both Assassins and eras that'd look weird. Not to mention that I don't see any point in having these eras if we're just gonna use the generic Assassin insignia for them.
Using an image not directly taken from AC was never really the biggest issue here; if it is something relevant to the time period (but not obscure), that will work. Like say the skull and bones for the Golden Age of Piracy, perhaps the Join or Die snake for the American Revolution, the kanji for each Chinese dynasty, a knight shield for the Third Crusade/Crusades, a guillotine for the French Revolution, etc.
I was actually thinking that if we do revise eras such that they actually correspond to eras, we won't have eras for different factions like Assassins, Templars, and the Instruments of the First Will. The main reason why I personally think it's fine to use Assassin's Creed logos for the era icons is because I see them first and foremost as Assassin's Creed logos not Assassin insignias even if they are generally synonymous. I see using the logos as no less appropriate than Ubisoft using Assassin insignias as the logos for the franchise.
However, if using an image not taken from AC is not an issue, then I agree that we can use your suggestions. The hanzi for each Chinese dynasty works better than my initial suggestion. (Though I kind of think that if we're just going to use skull & bones for Golden Age of Piracy or guillotine for French Revolution, we might as well use the AC logo with the skull & bones or the AC logo with the guillotine slash, neither of which are true Assassin insignias canonically used by the Assassin branches in the respective games even if the former is Edward's Jolly Roger).
