I agree, just remake those blocks and take out enough seams to get the wrong ones out and the correct ones in. It really doesn't take as much time as you think it will. Does it sound like I have experience???? Unfortunately, I've gotten to practice the art of taking out incorrect blocks and replacing more than once. You will absolutely feel so much better about the project when it looks right to you.
How about a picture??? A before and then an after would be neat.
