Here's what I did with mine. Just cut holes in the tank, each T/elbow goes into the tank then to line lock fittings. Move them around till it floats your boat or moves the poo. Can definetly get some surface agitation this way 
As far as the teeth, I hacked all mine out and replaced with egg grate.
If you run into flow issues (doubt you will) the full siphon overflows are supposed to move a rediculous amount of water through smaller drain diameter.
I'd definetly leave the one overflow on the end. I have one of the overflows in my 750 blocked and hacked (4) 2" drains into the one overflow just cause it seemed to move water around better.
I've always thought Korilias on a wavemaker or timer would be sweet but haven't had to resort to it yet. Something to just kick on to stir stuff up, but at the same time seems to me somewhat of a bandaid to cover issues that could be addressed with a creative return system.
