Kind of. Excerpt from this article by Ridley Scott:
“I think the idea actually came from Alan Ladd, Jr. I think it was Alan Ladd who said, ‘Why can’t Ripley be a woman?’ And there was a long pause that, at that moment, I never thought about it. I thought, why not? It’s a fresh direction, the ways I thought about that. And away we went.”
This was the late 70s. “Man” was still so powerfully default that Ridley Scott had not even thought of the possibility of casting a leading woman action hero before a meeting with an exec. That, to me, is clearly a gender swap moment, because until that moment, it was a given that Ripley would be a man. The gender-neutral script just allowed for the possibility.
Everyone likes him because the storytelling is good, which proves my point: Race/gender swaps are fine when done right. But when Miles Morales was first introduced, it was considered a race swap, and the usual crowd definitely moaned about it.
The multiverse explanation reminds me of people saying “But the elves liked being slaves!” in Harry Potter. Yeah, they were written that way, and they could have been written another way. The multiverse is being used to narratively justify a black Puerto Rican Spider-Man.
