It would be very difficult to match the fabrics. There are loads of current Thirties repros but wow, look at the fading. You'd need to was new fabric dozens of times, or bleach it, to get the lovely patina of age this quilt has. Your quilt has seen a lot of love.
If it were mine, I would cut it into good parts, and bind those. They could be framed or used just over the back of a rocker as something decorative.
