Some edge wear can be repaired. (also there is the possibility of taking them a part and sewing the ribbons on a foundation of grosgrain so you have a backing to protect the silk. It also sounds like your not into the shabby chic so a rescue may not be the course for you. What I would suggest is to find a good sewing person our quilter. maybe they can assist you in recycling the silk that is still in good repair, you might be able to get a belt or a pillow top out of them.
Something like this. If you want the design vertical you would have to cut and piece it.
