I would not recommend setting him up to kick at you, that is just giving him one more chance to practice his aim.
Carry a whip with you when you go in with the horse at feeding time and don't let him into your space at all. One hand for the bucket and one hand for whip, if he gets to close slap the whip at him, if he continues give him a good whack and drive him away, don't give him time to retaliate, just get after him. Then go back to what you were doing, if he tries to come back do it again, then dump the feed and make him wait a few seconds then leave and let him eat, he will learn quickly to stay out of your space.
Make sure it is a long training stick or whip, a crop or dressage whip is short.
