Typically, the debate that occurs about aborting is the question of whether one should always "GO" above V1; there are some very special scenarios where above V1, although the standard practice is to continue, and that's how the training is usually done, there could be scenarios where stopping on the runway above V1 is a better course of action.

But the idea of continuing below V1 (assuming you have mixed up V1 and V2) is a very different one. You're potentially looking at a scenario where the aircraft is below the VMCG speed, which means that if you keep going with takeoff power on the working engines, there's no guarantee that you can continue to track the centreline.

I think you'd need to have a very very good understanding of the real VMCG margins on your aircraft, and the margin from the scheduled speeds to the (real) VMCG, to consider continuing an OEI takeoff at speeds potentially below VMCG. And I'd suggest that most crews do not have (and could not have0 that level of understanding of the underlying design.
