Swap silver and nickel sorting. This has the effect of making green catalysts easier, solar panel 2's easier, amking solder casting III viable, making invar around the same difficulty as cobalt steel (which is really where it is tier wise), and making nitinol harder (which it should be). The only downside is that bronze smelting II is not really viable anymore, but it wasn't really ever viable to begin with, so I don't see it as much of a problem.
