Thanks for the replies. Using a FGB tile index without GTI/VRT unfortunately doesn't solve the problem since at some point the caller will still have to (pointlessly) transform the tiles, but thanks for the suggestion anyway.
The VRT connection string sounds ideal; I hadn't seen that before. I had been considering adding VRTs for each tile but tons of XML files lying around wasn't very appealing, so it's great that we can do that without the extra files!
