Não. "Tarkin" romance (New Disney Canon) por James Luceno indica que na conversa Tarkin teve com Dooku:
“I am committed to the idea of a galaxy ruled by an enlightened leader, with laws that apply universally—not one set for the Core Worlds, another for the Outer Rim worlds.”
“An autocracy,” Tarkin said. “Guided by the count of Serenno.” {{ DVK's comment - that was Dooku's title}}
Dooku gestured in dismissal. “I am ambitious, but not to that degree.”
“Who, then?” Tarkin pressed.
“We’ll leave that for another day. I’m simply trying to keep you from finding yourself on the losing side.”
Como sabemos da novelização do Episódio III, Dooku sabia muito bem que o Chanellor Palpatine era a mesma pessoa que seu Mestre Sith, Darth Sidious. Portanto, os planos para uma pessoa "ambiciosa" para guiar a galáxia sempre seriam Palpatine no que diz respeito a Dooku.
Isso é mostrado na mesma caixa de diálogo depois:
The count nodded in assessment. “I may not be able to forestall repercussions, Governor, but should this situation escalate to war between the Confederacy and the Republic, I will do my best to see that no lasting harm comes to your homeworld.”
Tarkin’s brows beetled. “Why would you?”
“Because in the end, you and I are likely to find ourselves under the same roof.”
Por favor, note que a frase "encontrar-se no lado perdedor" é uma pista falsa - mais adiante no livro de Tarkin é explicado que Dookan estava apenas testando a lealdade de Tarkin por Sidious.
{{Narrator's voice, showing Sidious' internal thought process}} Tarkin had remained loyal during the Clone Wars as well, enlisting in the military on the side of the Republic, despite repeated entreaties by Count Dooku — which Sidious had arranged as a test of Tarkin’s dedication.
