Would Unionville High School make an exception?

Unionville High School is a high school with a special arts program that you can only apply to when in grade 8 going to grade 9. I had decided to go to another high school because none of my friends were going to Unionville, but now I am regretting my decision! Many of my teachers have been telling me that I should have auditioned to get into their arts program. Unfortunately, Unionville does NOT accept applications in grade 10, 11, or 12. Many of my teachers and friends say that I am very talented and artistic and I also won the art award in my grade, do you think the high school might make an exception and let me transfer?
