You have minor recession and going to a good surgeon you could get a nice NW1 hairline. The question is Why not? You've been on meds for years which has near maintained what you have, minimal loss, perfect donor and assuming you have up to 10 grand cash in the bank there is no reason why you shouldn't do it.
People here are just comparing themselves wishing they had your head of hair and responding negatively to the idea of you getting a transplant. Go for it - with a credible surgeon of coarse. I've never heard someone say they've regretted a transplant when it's done properly, no matter how much or how little hair they had on their head to begin with
