For Pripara's case, it's difficult to say so. The recent story gives more emphasis on new generation while Laala and other old characters play a tutor role. The main reason why co-protagonist idea doesn't work well is that the game would tend to promote new characters or new brands, such as Yui's brand or Yui's team coords. KoF might sets a better exmple of focusing on both generations since it doesn't need to conecen about game marketing like Pripara do.

For fan theory... we we still need to see if the new characters attend a new school, otherwise itd be strange for people like Akari reject to attend Starlight Academy XD.
