Gorst, Ferguson, Pryke perhaps?
If I were The Crow, Roy Le Herrisier, Alan Breckon or even Ian Le Marquand, I would a) consider standing for CM and b) be heavily lobbying the new intake. There is the slimmest chance that TLS could be deposed. One would have to dangle a few promises of Minister/Assistant Minister (that the whole house ultimately has to approve) but it is feasible.
It is said that the advantage of the secret ballot is that nobody knows who voted for who. So, for example, Sarah Ferguson could theoretically tell TLS that she would vote for him.....then deliciously stab him in the back and get the Treasury job herself. Come on Sarah, you know you want to.
