Oh my I feel for you! I had something similar happen to me. I made the cake over again. I know you you can freeze the fondant but I dont trust freezing it on the cake I would be to affraid that the fondant would slide off the cake as it defrosted. And then the color bleeding would be a major concern. I truely hope someone can give you a way to make it work. But I have seen your cakes they are to beautiful to take a chance my advice would be make it again.
