The only problem is that they would have to stay active for pretty much the whole time. If I were a MOD, I'd get pretty ticked if the people who I elected as MOD dissappeared, and then came back, and then went away, and then came back and spammed, etc.
Though, I can't see the mentioned people leaving. Then again, if anyone remembers, I never thought Shadow 88 would leave, or Teh Master Cheif, or Spartan-288 (not the one with the GB in Halo-Verse), etc.

Outside kicking in the broken city,
there's nothing wrong with that.
