Which would leave every edge on the top and bottom along the whole piece as exposed bias.
Not a fan of that.
Unless it's paper-pieced. I know there are many quilts and blocks floating around with it, but I can't see adding a potential complication into the mix. ;-)
The pattern is a basic Seminole design - like this except with the rectangle is one solid fabric:
