Ideally, what black people should do is make an equally (or better) cool and charming original character (which wouldn't be hard cause white people like to flock to anything black they see as "hip" see: music, dances, slang/language, clothing, etc.). Black males are the epitome of masculinity in society so it'd be a very strong portrayal.
But it's already so hard to get a black actor as known characters in mainstream movies. It'd be near impossible to pitch an untested original
black spy/superhero concept to investors.
I see it happening in the future though.
