Yes yes old topic I know. But I would love to see this as well. Lets keep in mind however the current state of Rift. Something I have learned is that head position has not yet been implemented. You can turn your head side to side, up and down, but actually moving your head around has not been implemented. This is something I really hope to see in the commercial release, along with high resolution of course. DayZ would be the perfect manifestation of the Oculus experience IMO. Probably of the most "realistic" sim I've played, it would be amazing with realistic perspective.
