OK, the idea he would lie to the Viceroy is marginally plausible. But lie to DArth Maul too? What is the point? Your theory requires that everything he said in the film was a lie - to the characters, and the audience. That is bad film-making. It violates a basic trust between story writer and audience that is essential in order for them to suspend their disbelief while watching the film. In order to be lying to Nute about wanting the Queen to sign the treaty; he must also lie to Maul in telling him to get her to sign the treaty. In effect, you must make Sidious lie through the entire film to make your theory true. And Palpatine, too, for that matter. It makes both characters unbelievable. My theory, on the other hand, takes both characters at face value. My theory does not require some twisted interpretation of events / scenes / dialogue to be plausible. My theory is consistent with the events in the film as perceived without PRECONCEIVED IDEAS! Try viewing TPM without knowing they are the same person. Only a person who is already convinced Palpatine is Sidious can dismiss the consequent inconsistencies.
