he would be looking backwards imo
pretty impractical

Well, at last he'd know that Sidious planned to off him. He'd learn he's no match for Anakin and would have the possibility. He could flee while Anakin and Obi Wan release the Palpatine. Dooku would possibly return back to Yoda, atone for his crimes and return back to the light. He and Yoda would finally go to confront Sidious and, due to his knowledge and insight from the teachings of the Sith and believing himself again to be choosen one, he'd enter oneness while facing a manipulated Anakin while Yoda fights Sidious.
In communion with the Force, Dooku defeats Anakin, the false choosen one (in fact, a mere shadow of Dooku, the true choosen on - a perversion of the dark side in it's fruitless attempt to foil the desire of the Force), and following to help his old master against Sidious, delivers the fatal blow with a fundamentally sound (Tim Duncan style) makashi riposte, thus fufilling his duty as the true choosen one.
