Techcnially, I wasn't disagreeing, just asking questions where your description left out some details...
But if I were to offer something, I would say that the attack sequence you initially proposed (right overhead club/rigth kick) is not realistic becasue the swinging of a club with intent precludes the follow-up kick with the same side foot because of the weight distribution.
I would also offer my opinion that the idea of blocking at the elbow or tricep in order to cause a club disarm is dangerous because, should the hyperextension of the elblow actually happen, he will be releasing that heavy blunt object to continue its travel and that could take it right into your head. That is one of a handful of reasons I think that this is not a technique I would use even if it did mechanically work as you describe (which it may or may not, I am not sure - swinging a rattan stick yes, but try a brick, is the elbow aligned the same?).
David all club techniques assume that the brick, club, etc. goes flying out of the attackers hand on the block. We assume this because if it happens we need to be out of the way of the weapon. I.E. your head is always farther foward and to the left side so the weapon wont land on you head or foot. Any block done from the elbow to the tricep is very likely to make the attacker loose the weapon. We also assume they don't loose the weapon since if they don't we have to control them in some way that keeps them from continuing to attack with the weapon. I like your thought process. Your questioning of the logic of the technique will lead you to all the answers you need. If you don't like one answer keep looking I guarantee eventually you will get an answer that clicks and makes you go wow that makes sense or atleast that has been my experience. Best advice I can give is buy Professor I's videos on SK. They opened my eyes.
