Yeah, I don't think everyone in the series needs to be a physical power-house. Her narrative has long been one about her becoming Yoshimura's successor, and being a moderate leader that provides a home/shelter to ghouls. (Yoriko showing back up will definitely be important down the line, no doubt.)

Besides, ratings aren't strictly based on battle prowess. It seems like SS-rated Ghouls combine at least two of the following traits:
 * Incredibly strong fighter
 * High influence within ghoul society
 * Leadership of a major gang
 * High level of aggression (actively hunting Investigators)
 * Unusual traits/abilities

Touka isn't out there hunting Investigators for sport, she doesn't have any unique traits, and she's not someone with a ton of obvious clout. Even if she did get a major power-up, I don't think she'd be on the scale to be SS-rated.
