From my experience with manufacturers in general, most will not put a reticle in a scope that isn’t offered as a factory option in general.
As far as NF specifically, I highly doubt it because I had a 7-35 mil-r before the 7-35 mil-c was released. I asked them if they would do that conversion for me and they said no they would not.
From an optomechanical perspective they would have to resize the entire reticle for basically a 1 off scope. Especially since the F1 3.5-15 is discontinued.
Long story short I’d bet it’s a solid no.
