I'm not convinced for the same reason I posted above. The on-current is at least an order of magnitude higher than the off-current for all technology nodes that I know of.
The only way I see this having a significant effect is through the vt vs. speed trade-off I mentioned above. Lower vt's exponentially increase leakage power, so we push the vt up to combat leakage, but this reduces transistor speed because frequency is roughly proportional to the on-current which is roughly proportional to gate overdrive vdd - vt.
