So we know that all the Barbie and Ken dolls Mattel makes live in Barbieland. Dolls from the movies must be around, right?

In my headcanon there is a neighborhood in which only the movie dolls live in their castles and go around in their carriages, fly or swim (fairies and mermaids). The neighborhood is considered "high class", they are very private and don't realy get involved in the Barbieland politics. This is also the only place where Barbies and Kens are equals and have genioune romantic relationships like in their respective movies. That's becouse their stories "influenced" them in a different way then the other dolls. That's the reason they weren't effected or involved when Ken took over. They also don't call each other "Barbie" and "Ken", they all go by their movie names.

They could have their own meet and greet the way other rare "mascot" characters do. I'm sure they'd be very popular.

If not all of them, mabye just Pawbert could appear, but haveing the whole family would be awsome. A lot of cool interactions potential.

They could also make plushies of them, hopefuly in their gala outfits from the beginning of the movie.
