Un-Named MP Stages in old versions

[HPR]

I've done a lot of snooping around the wiki, and I have noticed some things. Since older versions did not have title cards for multiplayer stages, some stages exclusive to those demos have gone name-less. Because of this fact I've wondered what they might've been named if they lasted longer. So, what do you guys think these might've been called?
