Yes, I thought of that also, like Bonnie Hunter's Unity Quilt. However, if we are doing this as a group, I think it will be easier to do the same blocks as most everyone else. We will see how many sign up, so far there are only a few interested. I know their is another weekly quilt along going right now in place of the gal that did the Train Rides.
That center paper piecing is really a large project. It will probably take more than a week to put it together. I have not done any paper piecing since our last FW project. It really is not my favorite way to do these blocks, but I think it would be best for the center.
