TBF even Leninism is a stark departure from what MLs believe.
If you look at the original plans for the Soviet Union, Lenin was basically planning a Syndicalist Representative-Democracy. Problem was that Lenin got too bogged down in crushing any chance that said democracy would vote against itself, and then Stalin just decided to go full corporate town with it.

If you announced the program you’d probably have cities bidding against each other to host this department or that.
You’d probably have to create whole new departments just to appease cities and states that ended up not getting offices that you want to keep political capital with.
Establishing a Department of Language Accomodation in Queens would probably be the safe bet to test this kind of shenaniganery with.
