Indeed. Far be it from me to advocate actually employing one; I'd do everything possible to ensure one of these damn fuglifiers was redundant, myself.
I have a 10s billet cassette that I had a mate machine a few mm off the back of. It sits on a 7s cassette body I mounted on my RS-81 wheel, with the axle at 132mm. Non-drive spokes tightened a turn and a half or something like that. The Red RD clears the spokes by 3-4mm, even with the cassette overhanging the hub flange, partially due to the greater angle on the drive-side spokes.
