Possibly, that's an interesting thought. The main benefit of adiabatics as I see them is that, all else being equal, a process improvement of the RC figure can be used to enable either an increase in operating frequency or a decrease in power usage (this is reflected as the additional factor of fRC in the power equation). With traditional CMOS, this only can benefit operating frequency -- power usage is independent of the RC product per se. Supercondition (or near-superconduction) is essentially a huge improvement in RC which wouldn't be able to be realized as an increase in operating frequency due to speed of light limitations, so adiabatics would see an outsize benefit in that case.
