Could we? 0G is pretty rough on the human body (if you're planning on going back to a gravitational environment). And the truth is that beyond 1.198 years, we can only extrapolate what the effects are, as we have no evidence beyond that amount of time. Yeah, chances are we could go longer, but we don't know what happens until we've actually tried and measured.
