You can change the name to anything you'd like however changing the currency to Aeon can cause confusion among players. An Aeon isn't a form of currency. An Aeon is a billion years or power emanating from a supreme being. But not a form of currency.
Now most people don't know what an Aeon is. But most people get it confused with the MMO Aion
