Pity you can't make the fire animated, so that it looks like it's constantly burning 
Actually, i think you could! think about one of the sovvys that has "changing" bussard collectors. you could just make multiple textures for certain parts, script 'em to "rotate" and place em where the fire is most prominent!
...
although, i am no scripter or modder, so i dont know if it would be possible...
But! if it is, one of "us" could mod that ship, and do it!
that, would be freakin' awesome.
