I think the problem is not actually gods working through people here... the possible problem is that human mage channeled high test WAGH! a force fundamentally alien to humans. Its designed for use by mushroom/fungus men and not mammals. Basically, if your using winds, chaos powers, or god powers its all from the local warp. WAAGH! is not. As far as I'm aware WAGH! exists to dodge dealing with warp nonsense (it has its own nonsense.. so much nonsense)... the old ones being solidly anti-chaos warp nonsense and all.
So any issue stems from how the hell she managed to channel it without headsploding in the first place. The boosting divinity seemed happy with the results, but confused with the entire suddenly ninja thing. Hence the attempt at hiring thing. Kind of a desperate last ditch open ended boost anyone scrapping the ritual boost that found someone who wasn't even suppose to be there at all.
I'm not sure it could be repeated intentionally. It was just kind of a thing that happened. So wasn't an avatar thing so much as an improvised agent with nonstandard soul structure for the conduit.

On another note, I watched that Skaven origin video and give it 4.5 out of 5 Citizen Canes for nonsense writing. CC required someone to be in the room to witness his last words... and spent the rest of the set up explaining how he died completely and utterly alone. So the key point in the plot is a plot hole. The half point is because daemon princes were invoked in story and did nothing so it could be based on one of those daemon prince basically telling it as a comedic tale on open mike night. Once you establish the Skaven wouldn't have recorded that and no one survived to tell the tale there simply isn't a coherent narrative source.
