Would the gun choice make replacement cranes cheaper?

Would choosing a 14-inch 45-calibre gun instead of a 12-inch 50-calibre gun reduce the cost of the cranes needed to change it?

The difference would be too small to matter much: both weapons still require substantial cranes.

The comparison is between a 12-inch 50-calibre gun and a 14-inch 45-calibre gun. Both require substantial lifting equipment when their barrels are changed. The weight difference is judged too small to make much difference to crane costs, so cheaper lifting equipment does not materially strengthen the case for this gun choice.
