No, because unlike Rock those are even more sophisticated OoO cores than the Prescott itself. Quod licet Jovi non licet bovi.
However performance would definitely suffer if that ever happens so I don't expect it to actually happen unless that would bring some very obvious benefits like multi-MB L1D size or the clock frequency that leaves Power6 in dust.
