the P-factor and torque are indeed higher (in level flight) when the aircraft is heavier, however Vmc is defined as at full power on the remaining engine, so the difference is not applicable to Vmc.

whenever the total drag of the aircraft is increased the additional asymmetric drag of a dead engine is a smaller percentage of total drag and therefore has a lesser influence, decreasing Vmc.
