Impossible. Eve's dialogues heavily imply that all the souls in Purgatory are hers. That means she may be on par with the Leviathans. Even a human, vampire, angel trio could fend off a few Leviathan. Also, the Leviathan appear to be dispersed and only loosely organized. A powerful entity like Eve could perhaps ring in a few to her command (the low-levels).
