Just because Musume Ronshaku is going to be involved doesn't necessarily mean that Osana has the same storyline. Besides, suitors of final rivals should be unique yet hard to identify. Riku was chosen as a placeholder suitor for a placeholder rival. Osana is likely getting her own suitor, who likely isn't implemented yet.
