We toke out OC ninjas out of the game for a reason, don't see why you would create another.
As for izuna, why does he not have Name: Tobi? It's only a matter of time Lolz
But seriously, love the theme of these ninja pictures. They were brothers who worked together after all. But I say you should make Izuna a turn 4, with an effect that is alittle better then a +3 in combat for the turn. And Madara a turn 5 since this should be before he steals his brothers eyes, that maybe reacts to ninjas being discarded to combo with his brother.
