I think Daron made him vaguely more attractive in the show, LOL - Marco has a more upturned nose, his eyes are wider and his hair is a lighter colour. I doubt certain major facial features of the husband changed so drastically since his youth - so it's wish fulfillment again.
I also think it's funny how Marco is characterised as scaredy and overly cautious at first, but then suddenly defeats the fear of danger in an instant. Even more wish fulfillment.
The lady-killing is counteracted by Marco having to wear a dress at some point. I wonder how the husband reacted, I assume he's in on the fantasy along with Daron.
