I don't think Worthy Heroes changes your starting heroes. but it can change the heroes you receive throughout the game.
The MA Arco multihero is an Oeniad. The very good EA Arco mage. Very nice.
It is Epic Heroes, a MA only mod, which changed the 'scout' hero (I think) to a 'super' hero. I think MA Arco gets an Elephant Hero. Again very nice. But then most of the given starting heroes in Epic Heroes are. Thats the whole point of the mod
