So you assume, that Claudius himself was the head of the conspiracy? Well, he was perhaps involved. Claudius suddenly left the theatre a few minutes before Caligula. This way Claudius could hide, when the german bodyguards of the emperor went nuts and killed in revenge every aristocrat on sight. Did he know whats coming?
On the other side, Claudius was handicapped, and not what a roman would call qualified for emperor. If the senate could have agreed about a successor (some of them also closely related to the royal family), I doubt, the praetorians would have insisted to support Claudius.
That is what I meant, when I said, he was in a weaker position. Much weaker than Tiberius and Caligula before they were enthroned. So the senate had perhaps a chance to negotiate about details of Claudius' imperium. But this senate did not even try! Another hint, that this senate was surely not able to restore the res publica libera.
