Whole weekend style games?

Not sure if this has been done, please correct me if this is the case, and, not sure how feasible it'd be, but maybe at some point, someone could take the idea of a standard round and extend it to a multi-day long one, sort of combining the rules of engagement in team deathmatch with the around-the-clock, and long-term scenario posed by HvZ (except no zombies)?

I personally think it'd be kind of interesting to have a situation in which your players camped out over a weekend and had to deal with the "danger" of other players coming at their camp at night, and how, if this became common like HvZ, how people's loadouts and blaster choices would be affected.
