The whole point of V1 is that it literally tells you whether you can or can't stop in the remaining distance available. The general assumption is that you don't go flying with a problem unless you absolutely have to, so your scenario makes no sense. You could lower V1 to Vmcg if you wanted to, but then you'd be going flying in circumstances where it would be more prudent to stop.
