Good idea!
I would also suggest to add some larger machines (especially Electrolyzers and Centrifuges) that could be MultiBlock to avoid possible lags because of the huge amount of machines that are required at the moment. Then you could think about directly pumping the gases/liquids through pipes from one machine to another instead of using so many cells to transport them.
The processing array is a multiblock for that and even the single block machines allready use fluids, no cells.
