rome very clearly hit a tipping point where citizenship meant nothing, where it was no longer a carrot to encourage civic behavior among the aliens.  and this point was extremely reactionary compared to the universal birthright citizenship the west has right now. if you want your civic nationalist system to work you would need to a much more discriminatory system where one has slaves, aliens, client state, provincials, latin right, and finally full roman citizenship. one has to aspire to the legal privileges and responsibilities as they climb the ladder.  what you propose as civic nationalism right the fuck now looks fuck all like rome's classical system of extremely different legal rights based on your class.
