Yeah could work with some. People tend to stay in a situation with a set of beliefs until the (perceived) cost of staying becomes greater that the cost of changing. They will believe what they want until they don't want to anymore.
I've often thought that arguing from the position of agreement (at least hypothetically anyway) of a creator as your starting point and going from there may work with someone who still has some ability to reason and an ounce of personal integrity left, IOW a JW unicorn!
