A. The output shaft needs to be vertical
B. It would need to accommodate 2 small cims and maybe a big one also
C. It needs to be as short as possible meaning from the back of the motors to the outer plate of the transmission, hopefully around 6 inches in total length, I forget the length of a cim but the shorter the better
D. 3 or more speeds capable of being shifted without pneumatics, servo's or one of the small motors in the kit will be used. preferably servo's
E. customizable ratios.
Any advice?

Why are you so fixated on coaxial swerves? From the looks of your drivetrain last year it seems you were running each module on an independent Dewalt. Why not just put the transmission inside the modules?
I know 469 did this last year with the Dewalts, and I've even seen a dog-shifting setup before. It would certainly keep things compact.
