I would take them apart too. When I was making an Double Irish Chain I had trouble finding a green that I liked. Can't tell you how many I got done deciding I would just settle and then went to Rosie's and there it was the perfect fabric. It was a pain but I knew that while was never going to be finished if I didn't like the way it looked.
Also, someone once wrote that getting a quilt done is not a race, it isn't how fast you get it done, it is how well you like it when you do get it done. So do what makes you happy.
