Hairline lowering after failed transplant? (Photo)

20 years ago I had my forehead reduced with a hair transplant. Was not happy with the appearance. Could never tie my hair back. I topped up the transplant with more hair but I'm still unhappy. It's course, snaps easily and doesn't look thick and natural. Is it possible to have my scalp surgically lowered and still get a great result even after transplant? I will the surgeon find all my baby hairs? Can I reuse some of the transplant hairs?
