Green circuits for a big main bus, layout critique?

This is my first attempt at something this big. I'm starting with 8 belts of iron and 12 belts of copper, which should end up as 8 belts of circuits. 4 of those will continue down my main bus, 2 will make 1 belt of red circuits, and 2 will make 1/12th of a belt of blue circuits.

Before I start tiling blueprints, does this look reasonable? The bit on the right will tile to the right until it can handle saturated input and output belts (I think I need 10 copies at 1.0 crafting speed, less with modules and better assemblers), then I'll make 4 vertical copies each turning 2 belts of iron and 3 belts of copper into 2 belts of circuits.

I would recommend finding a a design that avoids using the long-handled inserters, I think those will slow you down once you scale it up.
