My thoughts: It's fairly obvious now that "Bigger is Always Better" is wrong. It would have seemed more convincing 100 years ago. Bigger is sometimes better. Small-scale production has some advantages. (Do I need to state them? I'll leave it to the reader as an exercise.)
If Big Communism and Small Anarchism both have their uses in their contexts, some sort of dual-track economy is needed, two parallel ways of organising the means of production.
I think the practical history of socialist economies has made it clear that there needs to be flexibility in the organization and modes of production depending on the sector. So yeah, a mix of federalized industries, ones with regional/communal control, and worker cooperatives/individual artisans at the smallest level.
