NJ, I think you will do fine. It's been almost 40 years now since I dislocated my ankle in a motorcycle accident. It was a serious mess. Had a spur removed 30 years later. Have arthritis in the ankle, but not bad. Jogging on it keeps it in shape.
But based on my experience with ankle and knee surgeries, I think at nearly 6 months after the break, you will be hiking like a champ. You may have soreness at times, but nothing to stop you. Go for it!
