Prime Sonny Liston vs Ali's opponents?

It's silly to transplant Sonny Listons short 1960-63 prime across two whole generations of heavyweight contenders from 1960-1981 but if you could do that (not get old, shop worn) and turn up prime for 21 years Sonny would do great. I imagine if Ali used only his Cleveland Williams performance each and every time, turned up as that young, fast 1966 guy with shorter hair even in 1981 he would never lose a fight too.
