I don't think it really fits. Sure there are some parallels, but also significant differences.

Eisenwald wanted to kill the guild-masters so they wouldn't be supressed. They only pretended to want to kill off a whole city to trap the Fairy Tail Mages. And they act purely out of petty self-interest.

Avatar on the other hand truly want to kill of an entire city. Sure it could still turn out to be a ruse, but they already sent their small-fry out to kill so I think they are for real. And unlike Eisenwald they don't just act out of petty self-interest, but out of religious devotion to Zeref.
