Maybe dialogue would be a more fruitful approach. Then one would know what the other already knows and the participants could only communicate the "deltas".
Dialogue is super effective for this, but it's also a skill: you're suddenly a teacher. You should have no judgement of the other not knowing something, and be able to effectively build up that delta in a way that is understandable and interesting to the other. This can be more difficult than it sounds, but it's also rewarding.
