Gearbox Design for an FTC Robot

BAG motors are not legal for FTC, though you could remove the motor from the AM gearbox and put it into a versaplanetary gearbox wth a 100:1 reduction.

Addressing the original question, I don't believe that this setup would cause you any issues as long as you keep in mind that the middle motor will have to spin opposite to the top and bottom motor for this gear train to function. As long as you mind that I think you'll be okay. If you don't mind me asking, what sort of mechanism is this gear train powering? Using three motors on one mechanism when you're limited to 8 motors seems a bit excessive. Perhaps you could use a larger reduction to accomplish the same task?
