Sorry to derail this endless debate but a tangent........
If any of those who you named could have risen to become the dark lord of the fourth age I would put more money on it being Saruman.
No way. Here's why:
1. Tolkien says "Sauron was the last incarnation of evil in Middle-earth".
2. Didn't Saruman lose most his power except his voice prior to his death?
3. The Blue Wizards. In UT, JRRT says, 'They were emissaries sent into enemy occupied territory (the East)' & 'I suspect they failed (their mission) in different ways, becoming servants of Sauron OR founding magic cults that outlasted his fall." That would make them Maiar with 'magic' cults of their own & plenty of Easterlings at their disposal, now wouldn't?
Oh, one more thought that dawned on me about the Herumur........
Doesn't Tolkien mention in Appedix A that 'The Descendants of Herumur & Ferumur were finally destroyed" by one of the Ship-kings or Umbardacil in the 3rd Age?
That statement seems to indicate a kingship was involved there........
'Men proved easier to ensnare. Those who used the Nine Rings became mighty in their day, KINGS, sorcerers, and warriors of old.....'
Hummm..........
