FF12, FFT and Vagrant Story is possible immediately.
Although I was the one who did orchestral and choral arrangements, FF Type-0 falls under the category of "might be difficult at this moment," and this is the company's position (in future, it would become possible eventually).
My personal answer would be that I want to leave this one to Mr. Ishimoto, who now left the company. He might do something with it by himself, and I would like to respect his artistic freedom as a freelancer
