To me the idea seems relatable enough to Michael Jackson's Captain EO at Epcot to at least be a good discussion point, or at least not an idea to dismiss as being too crazy to consider. She is amazingly popular main stream, and appears to be working with Disney in at least some capacity, with her special on ABC and her concert series on Disney+.
That being said, I think Chef is right in that making rides/attractions referencing "real" people is problematic, and from personal opinion, even more so now, than it might have been in the past. I was way to young to really have any awareness of social viewpoints related to MJ when he was Captain EO other than i thought it was a neat show when we visited Epcot. But it seems to me that back in the 80/90's and maybe even before that, you had celebrities/musicians that people liked, and the people who didn't just didn't like their music. But you didn't have the negative polarizing effect that i see in modern social media/culture, where in alot of cases, if you don't like someone, you are now against them. Your either team Swift or against her, as opposed to liking her music or just not listening. That makes any attempt to use a real purpose for marketing/rides hard, as your are going to have a built in ant-fan base.
