I love the fabrics you have chosen. If it were me, I would save myself the aggravation and simply make a quilt out of 8 or 10 in blocks and quilt it similar to what is show in the PB picture.
Coincidence here - my dearest friend (non-quilter) brought me the same pottery barn picture last fall and asked me to help her make a quilt out of it. She has selected the fabrics, washed, ironed and cut them, and as I am now back in MI we will be starting the quilt next week.
Good luck with your decision and your quilt. I know it will be gorgeous no matter what you decide on.
