CEA DLC Map Ideas

As we all know there is fairly good chance of getting more DLC for CEA/Reach. Any ideas?

Have to be from Halo, Halo PC, Halo 2, or Halo 2 PC.

Also, lets keep it at 3-4 maps, gamemode is your choice.

The Library (Firefight, Halo Campaign)
Danger Canyon (Halo PC)
Gephyrophobia (Halo PC)
Sidewinder (Halo)

Terminal, Death Island (if aesthetics are changed), Yoyorast Island (if possible), and Ice Fields (PC)

Derelict, Terminal, Waterworks, Colussus

Midship, Lockout, Chill Out, Sidewinder

Derelict, Rat Race, Death Island
