It is speculative but the visual indication on our screens is not a true representation of their size. They range from 250-400,000m in length which is much smaller then the “block” they occupy.
If we think about our solar system, the minimum distance of Mercury from our Sun is 46 million km, if we even take that as a whole system distance of 20 blocks across that makes the blocks at least 2.3 million km across. This is much greater then the biggest station (Centrepoint) so the probability of a hit should be - in my opinion - representative of that unless we are going to have data to represent how close to the spacestation the firing line to the target is and the accuracy of the weapon system.
I don’t think that will be sensible within the confines of the combine system. Therefore it should be a possibility but a minuscule one at that; almost to the point of not being worth the coding and development time.
However as previously stated this is speculative, but using sense.
