you can try it, there might still be a chance. Ive heard that you can cut clones up to third week in flower, you have to cut off the bud and leave some leaves on and it can still root and re veg. I assume its still possible with a ripe branch, if it will re veg and root, but its hard to say. Why don't you give it a go, the worst that could happen is that it doesn't root.
