Ok, read a bit more about herbies. Still havent read as much as I could about actually constructing one, but got a general understanding. Gate valve is installed to "fine tune" water flow to the sump so that can get a bit of an equilibrium in the overflow box where there is hardly any water sound to help make the tank silent.

Sounds good, but wouldnt I get the exact same effect with my design? I feel like the herbie results in lost air injection into the water. How is this remedied?

Ideally Id like to get a drain pipe that is turbulant inside it and a bit larger than needed so the water sloshes around, mixing with air, but remains quiet inside the pipe, rather than sloshing around at the surface in an overflow.
