Hmmmmmmmm... Slippage occurs because the tangential force due to the applied torque exceeds the friction force, which is normal force times coefficient of friction. Adding a second motor doubles the tangential torque force, so if Ft > N(mu) for slippage, I would bet that 2*Ft > N(mu) as well.

Your choices are 1) increase the normal force and 2) increase the coefficient of friction
