The normal way is to add some slightly larger object around the 
concerned object and fill that with a media using a spherical or 
cylindrical pattern.

Fog can't do what you want.

The outer object don't need to ba a larger version of your object. It 
just need to surround the part(s) you want to shine.

The fact that your scene is huge and that there are many glowing objects 
will make this tedious.

Clipka's suggestion looks promising, but will be computionaly intensive.
It may be possible to place refractive objects with averaged normals 
around your glowing objects. Low ior (no more than 1.1) and STRONG 
normals, NO reflection and NO highlight on those.
This way, the added computations are limited to the area surrounding the 
glowing objects.
It will render slower than the added emissive media objects.
