Copper is not analogous to saltpeter because Ironworking is the next tech up the tree from Bronzeworking. Theoretically, oil would be the "replacement" for SP and that comes way down the tech tree from gunpowder.
I agree with DH-Epic and Proteus pretty much across the board. Removing the hard resource cap on some or all production seems a particularly good idea. If that was the case, I wouldn't have any problem with the addition of SP as a resource.
