I wanted to help but I don't know how much time I can devote currently, but I do have some assets I would be willing to convert/donate for now to the project if they're of any use?

There's a couple of potential problems though, the poly counts may be a little high for this project (they can go up to I think around 2500) and these assets only have normal and albedo textures. Just thought I'd put this out there though.
