Would be nice. At this time, I 'd be happy with the ability to move cargo from one ship to another so I can change ships if the one I am changing to has the same or better cargo capacity.
Also, the ability to buy an upgrade module, specifically the FSD, for another ship, store it in the hold and fit it to the other ship when I get there. I currently have a Type 7, (seriously, a trading ship with a miniscule jump range like that as standard?) that's going nowhere fast simply because I need a better FSD with more range to get it to a high tech system to buy a better FSD. Two high tech systems that are within range don't sell them

. My other ship that can jump 3 times as far uses a smaller FSD so I can't even check if a system sells the bigger ones. It's totally stupid that we have no idea if a given system has what we want. Unless we fit the item we need to begin with, we can't get to the systems that sell the item we need. Right now, it is stuck in a 50 system or so radius where I bought it, every system outside of that is further than the ship can jump, even stripped right down. To add injury to that, I don't even have a clue where I can buy the FSD I need because I don't have a ship large enough to use one of that size except the one I want it for.
