I think it would look fine. SMP is also a great thing to do on your donor area to give it the illusion like nothing ever happened there, or make it very faint. If you get an FUE and then SMP and let your hair grow it wouldn't be noticeable. FUE recipients can use SMP just to minimize the contrast of the skin and hair, just for an illusion. I got an FUE, not a large one, 2500 grafts in 2014, i'm an NW2 now from NW4 and I think I would benefit from SMP at least in the donor area, that way if you want to shave the back of your head for stylistic purposes, the donor area wouldn't be noticeable. Look it up, there's examples of that. Now SMP on the hairline on top of FUE is tricker than just covering the donor area but from what i've seen FUE+SMP looks WAY more realistic than SMP by itself and even a small FUE by itself (large or multiple FUE's can look great with the right Doctor).
Another thing you can do is also FUE+SMP+concealer like Toppik. Trust me, that would work magic, I used toppik before me FUE and my god that worked so well. IF you use those 3 combined, you can look like a natural NW1 that not even your family would know what you did. Really, I would hate to get SMP alone, I don't like experimenting with permanent stuff like that, but FUE+SMP can work wonders. You need to see more examples.
