i already doing it with ships, flying it with push modules without going into the core.
its hard to fly like this, but it will be interesting if its possible to fly stations arround
IRL, NASA uses small jet propulsion systems to move satellites and other objects around while maintaining orbit. I don't see why this wouldn't be possible in game, but it wouldn't be fast by any means (as it isn't IRL either.)only draw back i can see with your plan would be that the space station should have a top speed of say 1 or 2, for the fact there very large structures not normally meant to be moved. But i think some logic that can support a tug like feature on your ships would be great.
