The point of this was to reduce weight and keep the single-shaft design; by adding a large gear and a second shaft it loses both of those advantages unfortunately. If I had to make a 2-shaft gearbox I would just make a regular ballshifter (like ABS-101, although I would probably increase the primary reduction if I were to go that route; that gearbox went a tad too fast for most).
