Black magneto wouldn’t work. Him being a holocausts survivor and that experience is a easy to understand and down to earth origin story. Updating that to a fictional concentration camp would have less of a impact.

And with casting of Nicky fury. Probably helps a bit that it’s Samuel l Jackson but also pre mcu the biggest marvel characters used to be x men and Spider-Man, most people wouldn’t have cared about nick fury.

But now…probably a different story.

As well as Jackson was most people’s introduction to the character of Nick Fury and didn’t know he was originally a white guy. Only the true comic book fans would know any better.
