The Guaido option will be pursued if there is not an anti-Russia government in Kyev, but it would fail as did the Guaido maneuver. Zelensky's global real estate holding alone, as a result of this war are disqualifying as a legitimate Ukrainian leader in exile. His $20m Miami mansion would look especially bad to make press conferences from. It is more likely that the CIA-NGO long game restarts after a Russia friendly government. A provision in the peace deal that was agreed to a month after the war start was that regions would be allowed after X years to hold referendums in order to join a side. This is key to not making Ukraine a nazi state determined to extract western weapons funding for its naziism, because no one votes for that shit.
