I'm pretty sure theres more to it than that, but I've never tried to do it, so arguing about it is pointless, and I don't think moving Hazard zones red-side is going to increase interest in red side at all, and it's going to require a lot of work blue side, moving GM spawns, rewriting missions all over the place that send you to said zones to make something that really doesn't gel with the rest of the red side zones.
Kinda irrelevant argument anyway, HC don't have the resources to do any of this at the moment, they don't even have the resources to finish KW and that was 80% done before they even got their hands on it
