Not very easily. Considering that Crom simply held off both Issei and Vali for 10 minutes, it's easy to say that Balor chose QUITE well when it came to him taming evil dragons. Thing is, Apophis is weaker than Crom, who was moderately affected by a dragon slayer-enhanced cannon, or Azi, who knows ONE THOUSAND kinds of magic, while Apophis is also the third most powerful of all evil dragons (and Vritra is the weakest) so it can be said for sure that Crom is going to have one hell of a time fighting both evil dragons.
