I think you're going to be fine. Using pasteurized juice with potassium sorbate would have initially had me saying "no no, that wont work"... LOL
I'm glad it's working out well for you. It may not clear up fully when it's done because of the pasteurized juice, but it would still be completely drinkable- just not as showy.
Let us know how it turns out in a few weeks/months!
