your making it too complicated with all that...
for glass:
setup a powered furnace with an import bus to give it sand.
setup a level emitter pointing at the furnace to "emit when levels are below limit" set amount to whatever (I use 512)
setup the furnace to run only on a redstone signal.
Repeat the process for cobble -> sand in a pulverizer.
Repeat again for bricks, or coal dust, quarried blocks, smooth stone.. or whatever other 1-step items you want
You may run into delays if you request something that needs more of an item than whats in stock - but its just a delay. the furnaces / pulverizers will eventually produce enough items to complete your run.
