I think so, because I would want like a place made out of iron ore and vines, and red flowers everywhere, someplace like that. just because I think that is cool, and pretty, and you know, just... just think about it. There could be chests with iron tools, and just iron in it! (Usually shovels) And I would want them to be rare, tho, just because I think it would be too OP with all that iron.
