BS_Agincourt: No. This is based on a 90's game which the original had so many programing holes that it wasn't funny. Sadly you've got too many stupid pilots that would unload all their proton torpedoes against an unarmed supply ship and then STUPIDLY commit a suicide attack against a frigate w/out ever firing their torpedoes for absolutely no good reason. This is the level of stupidity we're dealing with when it comes to game developers.
Likewise you cannot load more than one kind of torpedo/missile ammo. Believe me that I would love nothing more than to modify ships in some realistic way, like equipping an ion cannon to an X-wing or A-wing... but stupid or short-sighted developers never thought to allow the game to expand beyond a certain point. You'd have to know the game's code and actively modify it.
Why?
The X-wing doesn't have ion cannons in either the old or the new canon, same for the A-wing.
It's almost like the developers while tweaking things for gameplay reasons tried to stay as respectful as they could to the source material.
