I like the idea of a 4 at the 3 or even a 5 at the 3, as long as he can Defend outside, & run M2M. The only advantage of running that same idea with 2-3 zone is you'll get the Rebounding advantage on the Defensive end, but also the Offensive end as well. Problem though with that is, again, the reduced pressure on Ball handlers.
Right is not a popularity contest!
