[Star Wars] How would Order 66 have gone if Palpatine failed to turn Anakin to the Dark Side?

In this scenario I am assuming that Anakin followed Mace Windu's orders and stayed at the Jedi Temple while he went to arrest Palpatine. Also assume that Palpatine still defeated Windu.

The order would have still wiped out most of the Jedi, that was inevitable once the order was given by Palpatine. 

But maybe Obi-Wan, Anakin, and Yoda could have teamed up to stop Palpatine (assuming Anakin escaped the killing). Then there would be mass confusion throughout the Republic. Confusion about what to do when their entire military were suddenly outed as traitors/sleeper agents. It would likely leave them extremely vulnerable to the Separatists, assuming the remaining Seperatists could cohesively strategize an attack without Dooku. Grievous or Palpatine.
