Hi everyone, has anybody used a cast iron fireback to promote more heat out of a high efficiency wood burner. Is it even possible? Thanks for any help

No one that I know of. I don't see any way it could be beneficial
 
My first thought is that the fireplace is either under sized or not being operated properly if something like this seems necessary.
it wouldn’t reflect any heat, because heat isn’t being lost through the back of the fireplace. It was a common thought with a masonry fireplace because almost all of its heat was being lost up the flue, any little helps was the thought.
 
I don't think it will hurt anything (except maybe the carefully engineered airflow inside your firebox). If it's a freestander, you might get a little less heat out due to the extra cast iron blocking radiation in one direction.

You will definitely lose firebox capacity, so burn times and peak output both go down.

If you want to try it, let us know how it goes. I can't really see it being helpful.
