I don't know what all the quotes in your post prove except that Will is appealing to Kaysar's Achilles heel in calling his move "brilliant." I disagree. As far as I can tell James has not repeated this conversation to Kaysar, and probably won't. From all indications James and Will have an understanding in this game to cover each other's backs. James repeating this conversation to Kaysar would not serve Jame's agenda. I can't imagine James wanting Kaysar and Will to be "on the same wavelength", wanting Kaysar to get confirmation from Will, via James, that Kaysar's plan is good. The worst that could happen for James is Will and Kaysar coming to an understanding. In fact, Boogie suggested to James that CT and S6 have a meeting and James shot that down immediately.
If Kaysar's plan to get rid of the floaters was so awful, then James is playing the same stupid game. He put up CG and Will, after securing enough votes to ensure CG is gone. Of course this could all change if the veto is used, but I can't imagine any of them taking CG off. If Will is taken off, the Boogie goes up. Will would work hard to keep Boogie in the house.
Chicken George will be evicted this week and the game will finally be on. The floaters will have to finally play. No matter who wins HOH this Thursday they are going to have to take a stand and choose sides.
In my humble little ole opinion, Kaysar's plan is working, and it is indeed brilliant.
