Hmm, well, having the engines farther away from the central axis might make
it more manoeuverable (as you could steer in certain directions merely by
applying differential thrust), I’m pretty sure it would also cause the ship
to be less stable in straight flight. Unless your engines all had idential
efficiencies and output, the tiny variances in thrust would necessitate
constant minor corrections to remain straight. OK, so perhaps that’s not
exactly less stable, but certainly it would be less efficient.

If you go by pure physics, the fact that you’re in a vacuum would make
everything more stable, since there’s no real resistance. Besides, a
sophisticated self-guided missile should be able to auto-correct the thruster
outputs based on constant recalculations of situational events, rather than just
blindly assuming it’s going to go in the right direction if it goes at full
output.
