I don't think that would help. There's infinite tech to increase inserter capacity, I've done a few of those as a cope solution to increase inserter throughput.
But the reason I need so many isn't because they each need a massive amount of one resource, it's because they each need several different resources. A 2x2 giga inserter might help me load paper into this for example, but every other machine only needs 1 inserter to fill its needs, it just needs an inserter for 3 input products and 2 output products, so that's 5 minimum per machine, which puts me at 20 for the bottom 4 machines already. Then the red wire machines need about 260 paper per second total which is almost 4 saturated green belts.
I've seen people use loaders for this mod which will just insert stuff from the belt to the machine at the belt speed, but I think that's too cheaty, bob's inserters allowing this kind of nonsense is already pushing the limit, but without doing this the modpack would be near impossible due to the complex recipes.
