I agree with CalTran.

In 2011, we did the same thing with 8 inch wheels (traction in back, omni in front) but with a reduction between the gearbox and the wheels (chain). The robot barely had enough torque to turn. We ended up switching the CIMple boxes with Toughboxes since we were using a third CIM somewhere else that year.

If you have 2 CIMs or MiniCIMs to spare, you should really put them in those CIMple gearboxes. Unless you have a need for the CIMple box speed, you might be better off switching to the kit toughboxes. Even then, I would still put two CIMs in, otherwise you'll just get pushed around by everyone else.
