I think the syracuse staff would be selling STEWART he will be No 1 Inside guy surrounded by quality shooters in Buddy, Hughes and incoming class that can all handle and shoot with range.
Another option if that fails is chase Australian Sudanese player Kuany Kuany from Prolific Prep at the 4 and big enough in size to play middle of zone , in same mold as Akok AKok but more weight, or you have Damon Carrigan who could anchor the middle being a prolific shot blocker
