I loved that game! I remember spending hours exploring every square of every system. The challenge did fade once I decked out my eagle with full nomad weapons.
On topic. All they would really have to do is create artwork for a cockpit and overlay it with the power, targeting systems, etc. integrated into it. Then maybe move the camera to the axis of rotation for the ship so you felt like to were really in the ship as you moved around. The targeting reticule, movement and everything else would stay the same. Maybe over simplified but it just what I thought of off the top of my head.
