So I got the sump in last night, and it rocks! My goals were to increase the sump capacity (now 9-10 gal), separate drain and return pump chambers to reduce microbubbles and most importantly, have the sump fit in the stand and still allow bucket storage as well. All these were successful, and as a side effect, the noise from my overflow somehow decreased about 75%. It's now so quiet that I almost don't need to add my new overflow box and gurgle buster. Pretty cool. It must have something to do with lower/optimal backpressure in the drain hose. It is now about 2-3 inches below the surface, and totally unobstructed. Quite a nice change from that idiotic bucket sump with the drain outlet smashed up against the wall of the bucket.
