If there is game play to be had in getting around the cockpit and interiors as well as boarding other ships, how would 'Legs' work from a First Person Perspective? Would it be preferable, in terms of translating to already defined control axis', to have part of the pilots seat detach and be manoeuvred by jets? Smaller craft could decompress and have the canopy retract, whilst in larger ships, pilots exit through decompression chambers behind the doors. The 'Jet-Packs' could have Shields/Engines/Weapons similar to ships but on a much smaller scale, along with tool kits and handling devices.
This wouldn't address walking about in space ports or on planet surfaces, but it could be a start.
