It would need the gas giants to appear larger though - much larger.
As I think you know this is something I've looked into.
Planets and moons 3.3 times bigger is well tested now (by me at least) and would give one of the larger moon sizes (from standard redux for example) a size approaching that of a small planet. So the coriolis station would look big but likely not that much bigger than it does in the standard game.
However, if you were not interested in the ship rescaling work that I did (i.e. the 'cramped' range in ship sizes and large size relative to the stations didn't bother you) then there is room to double the increase to a factor of 6.6 which should give a pretty good result.
You could go bigger of course but (if using similar methods to the rescaling experiment) then it becomes easy to overshoot targets when using the torus drive. At x13.2 (or 6.6 with part III of the experiment included) for example, targeting the station is actually rather tricky.
If, on the other hand, you don't care if the witchpoint appears relatively near to a gas giant then you could make them much bigger. Could be interesting jumping into a system and seeing it dominated by a gas giant (might look a bit silly if you orientated towards the star though...)
