Maybe you have something in mind that I'm not thinking of, but doesn't central planning, even without waged labor, contain an element of external command that maintains some of the worst things about capitalism? That is, the abolition of waged labor might eliminate exploitation, but central planning would maintain mechanisms of control. The only way I see around this is for the workplaces to elect representatives to the central-planning bodies, in which case you are just extending the realm of crappyass representative democracy. That sucks. Shouldn't communism also eliminate democracy?
