A wonderful communication device, that keynote presentation is. It probably won't work.
Audiences are very perceptive.
They also know when the presenter is just giving a book report, having spent a little time in preparation to learn about the high points of the topic presented. When you are the keynoter, your audience ought to sense that you are not just a gallon of water, but, rather, a fountain of knowledge. We liked hearing stories read to us as children. But our audiences are adults. They want to experience what is in your heart and in your mind.
