Assessing the plausibility of Soviet Project 24 battleships

Which Soviet Project 24 battleship design was the most realistic?

The conservative 16-inch designs initially seem the most plausible, but the panel ultimately selects none of the schemes examined.

The 16-inch designs closest to Sovetsky Soyuz initially appear the most plausible options. Looking through the proposals leads to much stronger doubts, particularly about whether their armament and arrangements leave a ship that could float safely. One example is described as carrying twelve quadruple mounts of various guns. The final answer selects none of the designs examined. These are the panel's judgements during the discussion, rather than a demonstrated calculation of each design's buoyancy.
