The change to the engine mounting affects aerodynamic characteristics, not just weight distribution. The aerodynamic characteristics may have affected the stall risk.
The change to the engine mounting was due to the original low ground clearance (which meant less stairs for passenger and baggage handlers to climb before there were jetways and baggage loading belts) making the new larger engines too close to the ground (more risk of scraping). Media reports indicate that the nose landing gear with lengthened slightly, but do not mention anything about whether lengthening the other landing gear was considered as a solution to this problem.
