Then it turns out that Dooku is really Darth Tyranus and working for Palpatine. Ugh.
Here's my idea for what could have been. Dooku was really leading what he thought was the right side in the war. Yes, he might have been manipulated behind the scenes, but he knew that he was on the side of the just. The offer he makes to Obi-Wan is genuine, and not the last on he will make to a Jedi. The fact that he's giving Palpatine exactly what he wants then become a tragedy.
Even more of a tragedy is the fact that the Jedi, those lovers of peace and protectors of the rights of all beings, are on the wrong side and DON'T KNOW IT! The Jedi bring about, unknowingly, the destruction of the one group that could have overthrown the soon-to-be Emperor, or at least give a safe haven for all of those that eventually became oppressed under his rule.
Making both sides of the war under the control of one man just ended up with a much more boring story in the long run. Entirely in my opinion, of course.
