User blog comment:Observer Supreme/How would Kizaru and Aokiji operate if either of them were Fleet Admiral?/@comment-1784001-20170715041657

Kuzan would be a nicer person than Sakazuki though not as hard core. Borsalino would be way too absent-minded for the role. He even forgot that a Black Den Den Mushi is only used to intercept calls as seen during the Saboady Archipelago Arc.
