The 'Gateward Valley' which allows the recruitment of Centaur Chariots would work pretty well as a renegade Pangaea province. Enslaved Centaurs, Tyrant the Dryad (descriptive, but also a pun on "treant" - I really like this idea already), satyrs hoplites, revelers, etc.

Black Lord, Rogue Inquisitor etc sound a bit like modded units. New units can't be created in map files, which the province editor and SemiRandom work with, and descriptions can't be changed either. This means that while it's possible to set an Inquisitor with H2, B2 and perhaps some suitable LA Marignon commanders as a renegade Marignonese province, you can't change the Inquisitor's description or name to imply that he's renegade.

BTW, splinter nations would work well for small provinces. An inquisitor, 10 crossbows, 10 halberdiers would make for a nice, small addition to an indy province. All nations could have several such splinter provinces with varying commanders, national units and fitting non-national units. Abysians and Salamanders (and a fire site?); Mictlan Priest, Slaves and Jaguar Warriors; a Vanhere, few bodyguard Vanir and a Gnome; an Atlantian Consort, or perhaps a Traitor Prince helping a Toad Trinbe (i.e. toad tribe troops and the commander replace swamp defenders and poptype)...
