Thanks all for the info,
I've seen Paymaster's stuff and i think it may be a bit too heroic for this project as great as it is. Eureka's Tlingit are cool, but their fighting types might be a bit too early for the project. If they do civilians, I may be able to use some of those.
I have a feeling that this part of the project will come down a bit of conversion work and "good enough" thinking.
