Question: Make map in Unreal Engine, then convert it to Arma 3?

I dont know too too much now about Unreal Engine, I know the basics of constructing beautiful levels.
And I want to know if it is possible to create a map in Unreal Engine, and convert that level into an Arma 3 map?

This may sound like a stupid question, but I am just asking is this would be the slightest bit possible in any way?

Any helpful feedback would be much appreciated,

It depends on the workflow of getting things into Arma 3

You can export out an FBX of geometry from UE4, but that’s a really inefficient way of trying to build stuff.
