Remember, Jelly roll quilts end up with 32 rows. To add extra length, just sew extra strips together and sew them on the end one at a time to get it to the right length.
Here's one I did--started out with 55 strips, and added 8 rows to make it 40 rows long. That ended up being a little too long by the time I added the borders to make it fall low enough on the sides for a queen bed.
This is an UFO, I don't have time to quilt it right now.
Hope this helps! By the way, I love your choice of fabrics, and I think 60 will make a good size queen quilt, you may need to put on a border to make it long enough on the sides. As you can see from mine, I love batiks also!
