Legacy Edition as an Add-on

I know Minecraft won't bring back the Legacy edition, and for valid reasons. But If Mincraft could add them to Marketplace, to bring back the old crafting and other UI features. It could be like a mashup world, with texture packs, resourse packs, and the one to one replica of the tutorial worlds. Because right now people are downloading maps, and texture packs from obscure websites, that usually dont work, or are corrupted. I beleive, as well as many others to the commuity would love this as an edition to the marketplace. And Im also sure that devolpers, and map makers would love to help out if you would let them.
