Second Fitna Possibilities

So was looking to see if we had any good AH discussions on the Second Fitna, and it seems those we do have are pretty short, and focused on one of two scenarios: Islam fracturing earlier (here, here), or Zubayr prevailing (here), or the Alids (here). Anyone think a new discussion thread could offer more?
Here's another way of looking at this -- of the two more popular scenarios, the Caliphate fracturing longer term or the Zubayrids prevailing in the civil war, which one is more likely/plausible? And going with this option, what needs to happen for this to come about? And once we have that, what are the effects?

If fracturing the more likely scenario, how is Islam effected if the Ummayads have a region of control pretty much consisting of Islam's "Roman" conquests? If Zubayr prevailing is more likely, would this mean that the Caliphate avoids becoming a pseudo-monarchy as it did under the Ummayads, or does it just mean a different tribe controls the office?

Id say splintering via Ali being too lenient to Kharajite and them breaking off again. If Karbala went differently how long could the first fitna last

Wait, are you talking about the First Fitna? I was looking for us to discuss the Second (so preferably no PoDs prior to the death of Mu’awiya in 680).
