Could be cool, of course using these with large objects, like big ships and stations (if beyond the scale of a few blocks, or stationary) would probably move the astronaut instead. Like you shoot a wall in the distance and the beam pulls the astronaut toward it faster than walking/floating. This way you could use these to aid movement as well. Also, if these could be combined to one weapon (left-click pulls, right-click pushes) it would be cool to have a "Momentum Beam".
