If you want the seam to be lacy, then that would work--it would be easy, too.
My concern with leaving off the yo is the balance of the decreases. I made a shawl that had a yo at the beginning of every row, and it made a nice loopy edge. I crocheted a border into these loops, but I've never sewn together anything with an edge like that.
It looks like you're the pioneer for this one.
