I can totally see Ivan trying it and most likely failing.

But I didn't mean him holding information back from Zeref, I was meaning literal control over Lumen Histoire. Since he was most interested in learning about it's location from Laxus, I think Ivan probably wanted to steal it and I really doubt he planed to give it to anyone else.

I guess it's possible that Zeref may have hoped for Ivan's success and then planed to take it out of his (probably dead) hands, but Zeref didn't really strike me as someone who'd use Ivan for such a task, when he has the power to just walz into Fairy Tail and take Lumen Histoire by force.
