Well, you could have them all point to the same file to start with, and then have them point elsewhere as we add animations--just as long as we have the ability to configure them when required.
I've completed several animations already, if you want to take a look at them. Off the top of my head I can think of animations for...
a) projectile guns
b) beam weapons
c) non-beam energy weapons (plasma maybe?)
d) missiles
e) energy/plasma explosions
f) firy, gasoline explosions
g) concussive, stun explosions
h) explosions with lots of shrapnel
