Of course that would raise the question on how exactly the current team would get their hands on past Cure powers to begin with. Maybe the cards (or whatever they use) are more like backups that copy the existing powers stored in some far off realm that wound up being scattered for some reason.

Or they could just ape Gokaiger wholesale and start the series with a big battle that costs most of the Cures their power. The fairy for that season could gather up some of that remaining power and wind up passing it along to the main team. Maybe gaining the approval of the real deal would also power up those abilities, giving them access to more of that respective teams powers.

The crossover bits could be fun to see as well, they could learn magic from Riko, take a crash course in being a princess from Haruka, work part time at the KiraPati, see Nagisa and/or Erika freak out when she sees one of them transform into her (though the latte would probably think it was awesome), etc.
