Would the same simulations run on a wide-body 2-aisle plane (such as A380/777) have substantially different outcome? It feels like they board in the same amount

Would the same simulations run on a wide-body 2-aisle plane (such as A380/777) have substantially different outcome? It feels like they board in the same amount of time as a single aisle. Banning carry-on luggage that doesn't fit under the seat would be a great place to start.
