Just made this for personal use:

Gives you the ability to produce items from any vanilla metal, except clothing which is still adamantine exclusive. This mod can also be paired with my Dwarfium mod which you can find on my DF workshop page.

Other mods such as this are sure to exist, but I usually make my own mods whenever I need one and upload them. I'm sure someone will find it useful.
