Interesting but there are some flaws since not much is known about their histories as you know, other then they fought each other there is nothing to it other then the three factions had to stop their war to stop their fight. So they may have been able to kill some legendary beasts, but I doubt they have the capabilities to seal them after all they are more power then technique, also Vali and Issei haven't yet experienced the full powers of their dragons so I doubt they would need to absorb the legendary beasts since they would be considered one of the ten strongest beings which I think would be at the level of a super devil
