The only problem is that the engine is awfully weak at anything more complex than your most orthographic geometry. The Dark Engine was stretched, twisted and pulled to its limits for System Shock 2.
If I was going to try to build a Freespace FPS, I'd be doing it on the modified Unreal engine used in Deus Ex. It supported most of the same things the Dark Engine did, plus a bunch of others Dark couldn't do.
If I was going to do it on a modern engine, I would again go with a Warren Specter's choice: the modified engine used in Deus Ex 2. Why? Becase Specter and his team believe in making the software fit the story, not the other way around. There will be proper leaning, sneaking, sound trapping, shadow trapping, dynamic lighting, etc. In short, you'll be able to put together the sort of atmosphere you need for a squad of GTA marines skulking their way through a captured shivan ship. No other design team, in my opinion, can make an engine that can make that sort of atmosphere. Its what they're good at.
