From what said it should be possible to just wrap the code that is editor only into a #if WITH_EDITOR wrapper and the entire class would disappear from the build when cooked. I am not sure what happens to the data though if it gets stripped as well since it is now unknown data (or unknown actor in my specific case). I still have to test this but i had to put it on hold to work on some other stuff. Will try get back to it and report back at some point. Please do let me know if you find out aby useful information too.
