I think it would work fine if you cut and kit/stack each motif before you start piecing so you were sure your puzzle piece was all the same fabric. It does look simple. But my mind wonders why you bought enough pink fabric for a quilt when you don't like pink
The only one color quilt I've made was the reverse of my Dear Jane which I did in neutrals, but that was easy to design so each tone showed. I love it, but I wouldn't do another, I'd get bored.
