I think he would primarily be a NT, he played 93% of his snaps last year lined up between a 0 and a 2.
One thing about Saunders for this scheme is that he has sneaky length, with a wingspan:height ratio of 1.08:1. One common denominator across the Eagles front seven is that high wingspan:height ratio, I think their lowest is 1.08:1. Our lowest is Bresee, at 1:1.
