CHIMERA is working on converting the Iroe pantheon to Pathfinder 2e, since deities have a lot of mechanical importance in the system.
Here's the SRD: https://2e.aonprd.com/
For ancestries, any common Ancestries work, except maybe Leshy. Catfolk from the uncommon ancestries are also pretty common in Iroe. For Ghuls, I think stat-wise they're likely to either be ruled as Hobgoblins or Kholo, but I haven't investigated too much. For any of the other ancestries, talk to your GM; we can always add more races to the world of Iroe.
Common classes are all fine. Uncommon classes are on a per-GM basis, but as a rough guideline: Gunslinger shouldn't be a thing until after 4097 NA8. Inventors are generally fine past the 4000s, and will probably have connections to the Dustbowl Alliance.
