I suppose your eccentric input shaft might have a body that carries through, but that would complicate the shaft greatly and require a different "central" shaft for each stage configuration.
It's a cool design, thanks for sharing.

I was counting on it remaining concentric the same way the versaplanetary does, by constraining the gears with the pins, although it is possible to put a bearing on the output shafts if I extend the length of each stage and shorten the pin-holder output shaft block. I'm not sure if it's necessary, as the assembly is constrained mostly by the fixed ring pins and partially by the tranfer pins in a smaller ring.
The only alignment bearings right now are the ones on the output shaft and on any input motors.
