[Star Wars] What if palpatine turned obi wan to the dark side instead of anakin?

Let's say the jedi made the sensible decision of keeping a close eye on anakin during the clone wars, what with the whole prophecy thing going on. Palpatine can't get close to him, but he does know a jedi that he believes can be turned in his stead: obi wan Kenobi. It's tough, of course, but eventually he twists kenobi's sense of loyalty and a desire for peace into something far darker. 

Anakin, in a rare moment of freedom, is sent to kill grievous on utapua. Kenobi, meanwhile, goes with the other jedi masters to palpatines's office. Someone has tipped off the order that palps be sithing. However, doubt clouds kenobi's mind. At last, his fall to the dark side is complete.

What happens next? Bonus points if you could find a compelling reason for Kenobi to betray the order. Mine's a bit vague.

Darth Maul kills obi-wans love interest in the clone wars. If obi wan had been held prisoner by maul a bit longer, in time for palpatine to turn up, the emperor could have exploited the fear and anger caused by this traumatic event, and force obi wan to kill maul in his anger. As obi-wan, even as a sith would likely be more rational than Anakin, he doesn't make the same mistakes, still beats anakin in a duel so after the fall of the republic the emperor has a more powerful right hand man than Vader. There's also no luke in this universe so the empire doesn't fall to the rebellion probably.
