The emitters can deform quite a bit without causing render problems; remember, they aren't supposed to be seen anyway. Their illumination effect is seen, but not the emitter mesh itself. It may be that parts are outside the falloff zone and thus aren't moving with the pose, however.

If the emitter array is crumpling because of the low-poly geometry, you could subdivide it, but I think the lighter weight geometry is more advantageous (quicker rendering, less memory consumption). Another possibility would be to leave the emitter array as a dynamic prop; pose the doll and conforming suit, then run a dyn sim for the emitter.

A caveat for unseen emitters in general: they will show in reflections, or if viewed from behind a refractive surface. Avoid those situations.
