Like Nick and Ampk stated, you can apply for the 820...however, since you are on a BVA already, you will need to meet Schedule 3 criteria. I had to do this and it was NOT fun at all. It is hard to do and if I were you, I'd be consulting a RMA. Nick is a RMA and knows all about this stuff. I'd highly recommend you engage him (or any of the other knowledgeable RMAs found in the RMA sticky); because you do NOT want to go through this without help.
