In a Q&A, Kerry said there are several combat schools and only four Huntsman Academies (Like I said, Beacon, Shade, Haven, and Atlas are Huntsman Academies, not combat academies). This means that each kingdom has one Huntsman Academy and can have multiple combat schools.

So, I honestly think you could just make up a combat school for your OC and still keep it even if they do name a Vacuo combat school in the show.
