Customizable Lanterns

Now That We Have Copper Lanters I Feel This Opens The Opportunity to Create Custom Lanterns Where Depending on the Torch Used The Inner Color Will Change and Same Goes Depending on Whether You use Copper or Iron Nuggets Changing the 'Shell' Color Letting it Oxidize With a Soul Torch or Whatever Else You Want. This Could Also Allow For the Redstone Lantern, Though I Don't Know What Redstone Puporse it May Have It Gives Us Red Lanterns.
