I would also say Yuihan should count. Even the AKB0048 anime goes out of its way to highlight her the way golden era members typically get highlighted. There's a conversation between the trainees in it about a Yuihan who was an old Center Nova. I don't think they'd do that if Yuihan hadn't earned that legendary idol type status the golden era members are usually totted as having in the eyes of AKB's management. It's a moment that stood out to me in something AKB related that told me that at least from management's point of view Yuihan is as big a deal as many of the golden girls from the group's best years. And I am of the belief that a good chunk of people would probably see things similarly given her track record of activity during the golden era years. Even before the push itself she was pretty obviously a popular choice with people seeking to get to know members who were still relatively unknown which ultimately helped her rise quickly and not fall back down.
