Hey,
How old are you and are you taking medication?
I personally don't think it would be enough for good density but if you are looking to cover a bit of the skin then it would do that. my only concern would be that the crown is like an abyss and you can throw many grafts at it can still look weak. my plan is to give up on the crown and focus on the frontal third/vertex as this is what really affects my confidence and appearance.
Is your front strong?
