How can I use a UEditorValidatorBase to process game specific types?

I would like to run some data validation on the level that loops over all the actors, does some checking, and fires the result. The problem I’m hitting is that UEditorValidatorBase is only available to plugins which means that I do not have access to any types that are defined within our project.

Is there any way to do what I’m attempting here or is UEditorValidatorBase not meant to be used on game specific objects?
