Yes but it is against rules, and you may be banned from Halo and even your own xBox.
For "safe havens" infection.
Firefight: Arcade or Limited and Team Swat or Infection.
Mods are against the rules and conditions
only in halo reach you can to that

Ok so here's what you do when your in the options menu after you change the rules you press x then it should ask you if u want to save say yes and it should save ( I play halo reach tho so don't get too hopeful)
If You Mean change into elite, no, you can only do that in Halo 2, 3 and Halo Reach. But however you can use mods at halomods.com
As you progress in the Halo Reach campaign, the background changes. You can't change it though, that's the problem.
