TARDIS Idea

I was searching Planet Minecraft, and I found a TARDIS schematic, it made me think,
how cool would it be if notch made an add-on so you can make things bigger on the
inside?! SO say if you made a little hut out of planks, once you walk through the door
the hut is double the size.

UPDATE
--------------------
Since I wrote this a tardis mod has been made, infact, many tardis mods have been
made, so to the admin that said this wasn't possible, the nicest way I can say this
is.... LIAR.
