Still think the Liberty ship Hull wins, from the basic Liberty ship they got cve's
tankers, troop ships and all kinds of repair ships. Look at
this and you can see several of the diffrent varietys of the basic EC2-S-C1 hull.
Some of the later ships like the C4-S-A1 hull were built as troopships but after the war were converted to cargo and even tankers. Looking at the
blueprints you can see where the aft galley and stores were placed for commercial use. The midships area were designed to be ripped out and used as cargo holds.
One interesting conversion planned but never done was to convert the SS United States into a troop ship. Construction was actually halted for the conversion then allowed to be finished as planned.
