WI: Rapid Anti-Kabila Victory in the Second Congo War?

What would be the consequences of a rapid Anti-Kabila victory in the Second Congo War, before pro-Kabila government had time to intervene (Perhaps if the capture of the Kitiona Base and Inga Hydro results in the collapse of the Kinshasa defenses)? Would Uganda and Rwanda fall out, perhaps having a real war once the new administration picks one over the other? What other ways could the cards fall?
