A barbarian could still become an Emperor.

But after fifteen hundred years, is Jen really a Romano-Briton, or Anglo-Cornish?

An irrelevant question, as I don't recall the edict of Caracalla suddenly not applying. Ethnological lines make no damn difference, because the citizenry was composed mostly of non-Italians towards the end. Either everybody's a barbarian now because the Empire doesn't exist, or anybody from within its former bounds isn't. >.>
