It's a pity you can't SC between systems.
I don't see why dropping out of SC couldn't load the instance like HS does?
You wouldn't have to have the star close by as when SCing in some big systems it can take a while to find the other stars.
ie you are not locked to the biggest mass in SC as you are in HS so graphically it could be quite subtly implemented.
It'd be great for those wishing to drop off the radar by sitting out in a chest freezer of an almost switched off ship.
Another thing would it take more or less fuel to SC Vs HS to another system it might be a handy mechanic for those who can't actually jump so that you have a way of getting somewhere albeit slowly

as once away from gravity of a system you should be able to drift without propulsion.
(Ooops guess who used to play silent hunter in real time!)
