How well does SMP cover up FUE scars in donor area? Will the donor area hair/SMP look natural at grade 2 or 3 length? (photos)

I am considering getting SMP done on my 2000 FUE donor area scars before I undergo a second FUE procedure later this year of around another 2000 FUE grafts. My intention is to have SMP on my existing 2000 FUE dot scars, then go for my 2nd FUE procedure of approximately 2000 grafts, and then have SMP done on these new FUE scars. My question is therefore will this look natural as the existing hair in the donor area grows in and is kept at around 6mm-10mm (grade2/3) in length? Thanks
