I'm fairly sure there isn't a Jarvan V already because J4 hasn't had a kid yet... and i get the sneaking suspicion that that whole thing was kinda gotten rid of with the new lore.

but really, i don't think they'd do this kinda thing because completely changing the name and model of a champ would throw people way off... plus people would complain even more than they do now with reworks, but more in a tone of "why didn't you just make a new champ and leave this one alone", especially since all the ones you named would be for lore reasons, not gameplay reasons...
