or create a meteor object.. or a couple of them.

create a particle emitter

use the particle instancer (correct me if I am wrong) to attach the meteor objects to the particles (replacing the particles with meteors) ... Viola'

You might have to do a few expressions to rotate the meteors or to attach multiple meteor objects and stuff.. but you should be able to do it this way..

Gonna go try that myself to see if it actually works ...

later and good luck.
