I assume that a NW7 must still have at least 15000 follicular units, from which 6000 could be extracted for transplantation. A NW2 has around 40,000 follicular units overall, or around 80,000 hair. So a NW7 needs 25,000 FUs to become a NW2. However, it is well known that even 50% of density is enough to give an illusion of a full head of hair. Therefore, I think 13000 FUs would be enough, and if you don't bother about the crown, then even 10,000 would be quite good.
So I think a NW7 can be restored to a NW2 by the combination of scalp and beard hair, let us say 6000 scalp and 4000 beard hair. The surgeon could place more beard hair in areas where hair quality doesn't matter that much, like corners of the head and temporal peaks, and the area on top which is farther from the hairline.
What do you think. Is such kind of a procedure viable?

! And like you said beard hair is quite different, that is why it was my idea that only 30 or 40% should come from beard. If you have 70% scalp hair and only 30% beard hair, then I don't think it would be that obvious, plus you could always place most of the beard hair on places which are least visible, like I mentioned before.
