Calculate field and patch averages in multiple zones, large mesh

I have a case with a very large mesh (~ 50 million cells) and I want to calculate average data from patches and fields (wall heat flux, T, U). How should I approach this?
For smaller meshes I simply created a number of cellSets, called subsetMesh for each set and used simple OF tools to calculate those quantities. In this case, however, creating the sets would take a lot of time, because the whole mesh must be loaded for each set. The resulting mesh subsets would occupy a lot of disk space.
Is there a way to make these calculations in one go, or do I have to create and validate my own utility that basically will do what all the simple tool already do well? swak4foam doesn't sound like the right thing here, because I want to separate post-processing from actual solving.
