Your saddle and BB are forward of the rear axle, so they aren't going to be raised as much. So I don't think you're going to get a full 5mm drop with a 5mm tire difference...This ↑. Also, tires tend to be "wider" than tall, so a 5mm difference in nominal tire size probably means more like a 4-4.5mm difference in mounted tire height. A 5mm difference in nominal tire size probably results in a net stack difference of 2.5-3 mm. And a slightly steeper or slacker head tube angle, depending on which end of the bike you mount the bigger tire.
