I think it would be best to come up with some 'easy' form of unrestricted access to Hazard zones like an crack in the war walls that isn't mapped but anyone can go through. It's a good idea to limit it in theory, but it skews things heavily against hero-side since villains have a mere 2 hazard zones to the heroes' more than 8
-edit- Maybe make a low-level mish to get a fake ID, as sort of a Vigilante 101 arc. Get a fake ID, take something froma hazard zone in paragon to a place villainside or something like that.
