OTL, Marin Falier's insurrection failed because of tipoffs.
But what if his supporters managed to reverse the republic's government and impose Falier as hereditary ruler?
Would he became sort of a medieval Cromwell, a hiatus within a regular government, with a quick restauration of the medieval republic system?
Or, at the contrary, Venzeia would be ruled by an hereditary ruler as a new system. And in this case, is the city able to remain independent from HRE's grasp or is it would became sort of Great-Duchy, as Florence OTL?
