What was the simplest way to improve Bearn?

What single, simple change would have improved Bearn most?

Use two lifts of one standard, well-developed type instead of three different specialised lift designs.

The simplest improvement would abandon the three specialised lift types. One well-developed lift design, installed twice, would simplify spares and operating cycles while freeing the hangar from incompatible arrangements. Standardisation would directly address a ship whose clever mechanisms impeded aircraft handling.
