To be honest, it looks like you planned for staggered strips. Just go with it, quilt it and I seriously doubt anyone will notice. I like the pattern, you should be proud of your design. Don't beat yourself up, I was cutting strips for a family reunion quilt, and when I started to do the piecing, I hadn't cut them wide enough, so I just clipped them together, and I'll use them in another quilt. I didn't have enough of the background fabric in any case, so the white backgrounds were different fabrics and nobody noticed, besides it was a scrappy quilt to begin with.
