Selectable co-op characters and classic?

Here would be something interesting.
You can choose who to play as in Co-Op. It would be very similar to how you change teams in Halo: Reach. RB just changes your character. Of course once a character is taken, they can not be chosen again. Example: You won’t have two arbiters running around.

ALSO
Why not have special skulls that give you unique co-op characters? You can play as Arbiter, the two elites from Halo 3, Johnson, classic John (Mark V and VI), etc.
This of course would be non-canon and just for fun.

Think you’ve smoked a bit to much weed.

I wish they would limit the people here so you could only make 1 thread each hour. Then this guy would be limited to only 24 threads each day.
