Likely. Unless that Constantinos at least looked somewhat good? Don't know. But is he the one who was on the throne in the 1040s (unlikely) and pretty much allowed the (hundredth) civil war to take place, with almost losing his head when Georgios Maniakes marched to Amphipolis with a serious army? Maniakes won the battle (and the war pretty much) and was meaning to decapitate most of the nobles in Constantinople and install himself as the new emperor. He was a sort of 'The Mountain' (including gore), had conquered lands for the Empire in Sicily from the arabs, fighting alongside Harald of the Sagas (who afaik regarded Maniakes as a giant too). But he was so over-confident that he will just break everyone's skull that he charged alone in the end of the battle near Amphipolis, and so got wounded by arrows, died, and the civil war ended like that. Of course, only 30 years later, there was a minor setback for the Empire, in Matzikert.
