NEVER..V1 has ALWAYS to be higher than vmcg.
It's a regulation requirment that states that:
V1 must be equal to or greater than Vmcg
VR must be equal to or greater than 1.05 Vmca
V2 must be equal to or greater than 1.10 Vmca
If you want you may check this discussion about V1 and VMCG.

Imagine to have an engine failure after V1 and you have to continue the takeoff run. If your VMCG at this stage is higher of V1 you would not be able to keep the aircraft on the centreline with the remaing engine on T/O power! (without exceeding 30feet of desplacement and without using the steering wheel) So that's the reason we must have VMCG always lower or equal to V1!
Hope it helped!
