If you want to change the rank, there are only two options.Can degenerated from the Great Powers or degenerate into a Major Power.Spain (19th century), Qing Dynasty ( early 19th century), Ottoman Empire, Austria-Hungary, Russia ( early 20th century).This rank will have bonus with military and economy technology.If they do not participate, they will lose a lot of prestige, and eventually they will degenerate into Fallen Great powers.
