High tech contact lenses that make Batman's eyes appear opaque white would solve the problem of the actor not being able to emote with their eyes. The actor would be able to squint and widen his eyes accordingly to give that comic/animated series look.
You can make up any excuse you want as to why he wears them. They could be HUD displays feeding him info visually, night vision, etc.
It could look really good paired with the black eye paint and cowl.
I don't know how to manip, but I wouldn't mind if someone took a shot at it.
