Can we see a picture of what you have? Someone may have a solution for you. I think there are a few here that are visual, myself included. :D Do you want the width of the strips smaller or the blocks themselves? the blocks themselves would be easy remedy , if it width it would just take some time ,but I think possible.
Just re-read your post, see you already have two rows sewn,So my vote is continue on, remember they look so different when you see the overall pattern and once it is quilted it will look different also.
