You know, Namor doesn't need an excuse to have a beef with most male characters. It's kind of his standard opening attitude. I blame HIS grandfather for that. LOL!
I guess it would depend on the set up. But my main problem with such a team up is it would be Namor supporting Black Panther, yet again. There hasn't been a single story I can think of that is told from Namor's PoV or about Namor and Atlantis, with Black Panther playing a supporting role.
Also, I didn't care for Hudlin's continuity ignored, handling of Namor and T'challa's relationship or the WWII flashback sequence with Namor and Azzari. Namor can be impetuous, but he isn't stupid. I prefer Priest's take on them, where they are political frenemies.
