The original question implies that the aircraft is ASDA limited. This could be overcome by reducing the mass. This would not reduce Vmcg so V1 would remain at the stated value of 100 Kts.
But at the lower mass the aircraft will accelerate and decelerate more quickly. This will reduce the distance required to accelerate to V1 then stop (ASD). This might be enough to enable the take-off to be carried out.
