Dukat? Nah. Alaimo's fab, don't get me wrong, but when it comes to men, even fictional men, I just can't get into a guy who's that into himself. He's also a total tomcat -plus there's his weird Bajoran female thing. And finally, he's a monster. A charming monster but a monster nonetheless. So...no. Definitely not.
As for Cardassians, I'm not sure I can help you because actually Vulcans and Romulans are my favorites.
