In the recent 0.0.903 update we got the features of the Overload mod however it doesn't allow you to edit the XML properties of the Astronaut like the original mod does. Not sure if this is just a bug and will be fixed but if not it should be implemented.
This feature can come in really handy for resizing the astronauts, editing their mass, as well as editing their jetpack fuel power/fuel capacity to deal with EVA's on planets with high gravity along with other scenarios.
