Include April Fools Texture Pack for Free

A few years ago Mojang redid all of the textures in Minecraft.  I'm not talking about the official retexturing, I'm talking about the April Fools retexturing that Mojang did prior to that, which included very weird and bland textures.  I think it would be funny for this to be included in Java Edition, along with "Default" and "Programmer Art."  Perhaps it wouldn't normally be there, but typing a certain keybinding would bring it up, like how typing excitedze in a recipe book changes the language to pirate speak or how holding CTRL while clicking on World Types brings up the Debug world.  It would be awesome to have access to these weird, wacky textures in vanilla Minecraft.
