Forgive me, but what is the problem with the current rule? Any kick, with the lone exception of a scoring attempt, that is touched by a member of K, in the EZ and (somehow) caroms through the goal is dead, or a Touchback.
You could change the rule to suggest that any scoring attempt kick, that is touched by K, in the EZ, and caroms through the goal must be an act of divine intervention, and therefor is allowed, but that would likely cause some, very possibly the same few, to raise concerns on Constitutional grounds.
