Mainly out of boredom, and in a pursuit to create something that was smaller and cheaper and possibly lighter than a AndyMark Supershifter. SuperShifters will probably be used due to the ease of obtaining them. This is as much design ideas, as practice CADing full assemblies from scratch. Chain drive does give the ability to alter the gear ratio as you pointed out. You also lose some efficency with running 2 CIM's on one shaft because one is always working against the other by a very small amount.
