The math pencils out, but the station has to have a fairly large radius away from the axis of rotation. For example a station rotating once a minute with a radius of 500m produces 0.6g. This means that you are looking at a 1km diameter if the station is symmetrical, or possibly less if some sort of counterweight is setup.

Not at all implausible with current technology. Two habitats connected with a tether would do it.
