This sort of system comes around regularly every decade or two. Sachs (I think?) had a 3X7 system back in the '90s, and before that someone manufactured adapted drivers for SA hubs that with longer axles accepted at least a 3 speed fw. When rebuilding an early Varsity I converted the drivetrain to 6 with a standard AW and two ordinary SA cogs, one an 18 reversed, dish inward, the other a 16 dish outward, and held on by tack welds to the driver -- this circa 1971 or 2. It worked very well with a Benelux pull chain rd.
This sort of conversion made sense back in the days of pull chain rds, but with modern derailleur drivetrains with such wide ranges and so reliable, durable, and efficient, I wonder what advantage one would have with such a hybrid system. I seem to recall that the AW has relatively little internal friction in indirect gears compared to more sophisticated models, but this would leave you with the external complexity of a derailleur system and the friction of an internal system, no?
