Is possible, but you need some good guy that now well the vehicle code of multiplayer and singleplayer both.
the asteroid mod of gummelt have a nice multiplayer dogfight space combat.
the single player vehicles are horrid and hacked. animals and speeders are very good both Fighters handling and collision is very nasty.
well, basically, a coder should past the source code of asteroid mod from MP to SP for fix the bad flight behavour of fighter.
then you need another problem: you need to wrote an AI for NPC that use fighter vehicles for have realistic space combat mode. hone
