This all seems to go against some key founding principles of the USSR. Firstly, the ban on factionalism/Democratic Centralism, which means the idea of factions within the CPSU is pretty unlikely, as anyone in a strong position at the top (ie like Stalin in the mid-1920s) can easily dictate what equals the party line and what ocunts as deviation.
Then you have vanguardism, the basis of Marxist-Leninism, the idea that the Bolsheviks are crucial to socialism taking root in society, such an idea pretty much kills off any real chance of industrial democracy. Even post-Stalin this was central. Look at the 1956 Hungarian Revolution, during the more ambiguous days of the crisis when Kruschev was weighing whether or not to crush the new 'reformed' socialist government, one of the things that appalled him was that factories had thrown off Communist overseers and shock workers and organised apolitical coops, a good Bolshevik such a set-up was anathema to him.
Also decentralisation is not on the cards, definately not with Trotsky (people forget Stalin pinched his ideas for rapid industrialisation and collectivisation). Got to remember the 1920s/1930s were a high period of technocratic ideas and Lenin was heavily influenced by corporate scructure and Fordism, he looked to Detroit for examples of how to build an efficient, top-down modern economy.
To create such a system your best bet is with the Socialist Revolutionary Party who non-Marxist, and saw the peasant commune as the basis for a socialist society, I can imagine they would encourage something similar in the factories. Meanwhile given their electoral results in 1917 and if they pull off land distribution well enough they might end up the rulers of a one-party democracy ala India, Japan and Ireland.
