Yes! I have an uncompleted Bonnie Hunter Mystery quilt. I ignored Bonnie's colors and made it using Christmas fabrics. The individual units looked great but I disliked the pattern when it was revealed and my version made the pattern look even worse. My quilt/blocks/units are sitting in timeout while I work on a solution. I have revisited it a few times and my opinion hasn't changed. When I have time and feel creative, I will take apart the blocks and play with the units until I find something that pleases me. Possibly I will split the units into two different quilts but I will rescue those blocks. Too much effort and time was spent making them, to not have a successful quilt.
My advice is to unsew your quilt, and take it to the point that you last liked the pieces. Then rework the blocks or units until you are happy. Have you considered using the tulip rows, as a single row, in a backing for another quilt? Depending on the number of rows/blocks, you could get 4 or 5 unique backings.
