Don't see much point to "space legs". You could wander about the station from office to office to meet contacts that are currently on the missions board, but you're basically just going to go for a sit-down meeting with them, so why not just give us a station map and jump to the relevant locations if the atmosphere of a meet location is important. Walking from place to place will get very boring, very quickly.
One of the things I love about Galaxy on Fire HD is that even a simple iPhone game from 2014 had places to go once you got off your ship. Sure you're just standing there, and chatting, but it really added to the ambience to the point that the GoF galaxy felt so much more alive than the ED galaxy.
Boarding/exploring derelicts is more suitable, but would more realistically be achieved by controlling a drone - would you really put yourself or crew at that kind of risk?
Aside from the drone mentioned previously, I think we'd be better served for small-scale activities outside the ship by "space arms" rather than "space legs" - I'm thinking something like the pods in 2001: A Space Odyssey. Would be easier to implement too - and replace limpets for some tasks.
On-planet the SRV is better than space legs as it gives you speed of travel, in space a pod would allow most 'spacewalk' type activities. Where is there any real gain beyond those by going spacelegs, which requires a whole different movement mechanism. Walking about also doesn't really work very well in VR - vehicles do.
I also think introducing space legs will lead to Elite rapidly becoming yet another variant on the first-person shooter - given the demanding nature of PvP players.
Interesting take... have to be careful of that FPS lot.
I, personally would be satisfied with what you stated... Click somewhere on a station map and you go there, like you do when piloting your SLF or SRV.
It could be the security office to receive your bounties.
It could be the outfitting station where you're standing OUTSIDE your ship looking up at it or on a moving gantry looking down and watch as robot arms load and unload weapons etc from your ship.
It could be the seedy black market den with an onionhead smoking dealer sitting nose to nose.
You could click on each faction and be instantly transported to their hq building /back alley dealing rooms etc depending on their wealth and status which would dynamically change... You'd be seated in front of the NPC instead of staring at a static single frame rendering of the generated NPC.
It could be the refuelling and repair station where you get to watch the drones repair your ship and repaint it.
It could be the commodities market trading terminals, selecting stuff to sell and buy or the trading station.
All the things you buy get stacked up in the warehouse and the final "Load ship" button sees them all get carted off by drones/conveyors towards your ship back in the dock.
You could start off IN a prison cell in one of those detention centres and click "Request permission to leave."
These next three could quite easily end up as screensaver/chillout/timeout places while you wait for wing mates to arrive or IRL coffee to brew instead of logging out:
It could be the observation dock where you get to look out of the window and watch ships coming in and leaving through the maillot.
It could be in the park next to a fountain where you look up to see the massive ships flying overhead and parking in the cylinder.
It could be on one of the habitation wings where you look up to see the orbital rotating slowly.
You could just be standing or sitting there in each scenario... (With wingmates/multicrewmates/NPC crew) and use the camera to take photos of everyone in their get-outs.
No need for any spacelegs as such. It would add little gameplay other than ambience, but the stations are SO DEAD that any improvement would be more than welcome. Of course, there could be the option to walk through the corridors manually or hop on one of those automated yellow trucks, for those so inclined. As someone in this thread said, they should be an option, like horizons rather than forced.
