I think with T'Challa it would be tough cuz "The Other Side" was very much about being a minority in America in real time and BP is literally a head of state. And his portrayal in the comics over the last a couple decades ( or at least since Priest) has been as an equal if not superior to Stark, Cap, and Thor. What might be interesting though is in digging into that brief period where he was high school teacher in Harlem.
Having said that, in real life back in the 60's-70's there was a strong Black Pride movement where African Americans reconnected with our African roots. It would be cool to see how Sam Wilson and Luke Cage might have looked up to Black Panther in the early 70's.
