It is possible.... it could happen.
it may depend in the creative mind of the designer or the concept they want to mesh in the show... It could happen in Seoul.
As seen usually, runway models chosen for NY, Paris, Madrid, London and so on are usually tall, have experience and are connected to internationally known talent agencies. To be connected to the well known designers and fashion houses like, CHANEL, Balmain, Dolce and Gabbana, Versace, Prada and so on is a prestige alone.... There is fierce competition amongst the international models to be picked by a certain designer or fashion house... Not all the models get to be the first to open the runway or the model to do the final bow with the designer. Popularity also plays an important role... to attract interest and exposure. Think about Kendall Jenner as an example... she is considered a "super model" while one of her besties, GiGi Hadid, another well known model, may not have the same demand as Kendall.
Fashion world is a bit complicated, I'm afraid.
