you can not break OHMs law , no matter how hard you try .

but
it will not change your FE more than the noise in your FE calculations
Ohm's law also says

Power consumed = Voltage * Current, and Current = Voltage / Resistance, so it can be restated as

Power consumed = [Voltage]^2 / Resistance

As resistance increases, the power consumed decreases for a constant voltage.
