SWC DDC TOP comming up - tests prove better than Alphacool, DDCT-01s, XSPC

Yeah, it's a great idea. I was always thinking some sort of special rounded/T like endmill would be needed to do that, never thought of making it in more than 1 piece. This should really help direct the flow off the impeller vane plane and concentrate it to the outlet. It's also a great way to get around the diameter limitations of the o-ring.

It is called a radius keyseat cutter. This design could easily be done in one piece with the right tooling. Honestly I've already seen how high the impeller outlets sit out of the housing on the DDC's; I've considered something along these lines before.

An intersting note... this design change will only benefit spiral volute designs; IMO there is not enough pressure differential around the impeller on a round "high-flow" style design to cause a major performance increase. There isn't enough propensity for backflow.
