Yeah, just be careful because those grafts could be more useful elsewhere. I think chasing a youthful hairline to excess creates problems in the future. Think 40, 50, 60, and beyond. A little recession looks good on many people and it's an indictator of physical maturity. It also guides the natural part.
And keep in mind the rule of thirds. A forehead that is shorter than the length of the nose tends to look less balanced.
