You can't successfully choreograph jousting. Tog can advise someone to aim the lance lower, higher, to the left, blah blah blah. You can't choreograph it, though. Fits on the ground between people, sure. You can even do it with some success with skill at arms events and mêlées.
There are, however, ways to make jousting passes and hits as safe as reasonably possible. You can even do it while remaining period correct. The biggest is to use breakaway lances and balsa wood. Some others are well-fitted, correctly made, full armor, helms meant to protect the face from splinters (though they can decrease visibility, so it's somewhat of a double-edged sword - pardon the pun), shoulder guards that are securely fastened and fitted to the armor, and it's even a good idea to use light armor to protect vulnerable areas of the horse.
Just some things to think about.
The wind of heaven is that which blows between a horse's ears. ~Arabian Proverb
