I think the main reason they're not included in concerts is because they're not Crypton's characters. "Officially recognized" only means that they're allowed to be sold as merchandise alongside the other characters. That does not mean however that Crypton fully owns the rights to them and they require permission from their creators to be put on concert, for whatever daft reason they want to do that.
