2 CIMs into 1 Modulox

Does anyone know if there is a " two into One" type gearbox that we could feed a Modulox lunch box with ? We would like to try the CIM/Mini CIM combo on our Mecanum.

Just buy a pair of 2 slot plates and two more motor receivers. Modulox is designed to be flexible so it is easy to add extra bits onto the gearbox.
