This is one of those things that should be easier than it is.
In practical terms, I agree that it will be fastest and easiest to just work in your main comp, then duplicate it for each camera and manually select the camera for each comp.  

The other option only works in some situations, when using 3D layers.  If this is you, then you try doing the opposite of what you suggested.  It’s your “master” comp that becomes a precomp in 6 new compositions, each with one camera in it (that can be linked to the master comp via expressions).  The you enable collapse transformations.  The problem with this approach is that it only works for AE 3D layers, not camera-aware plugins like Particular etc etc.

I have a need to have six cameras in one master comp, looking in different directions but rigged together so I can move the camera rig easily as one e.g. with a null.
 
I’m messing with the multiple comp, single camera method and it’s very awkward.
 
Of course, AE only will render the top camera per comp. But is there a way to feed output from all six cameras into another comp that would be a preview and render comp i.e. made of six precomps of the output of each camera?
 
If you switch the active camera, AE see the output just fine for each camera layer in a comp, so I figure there has got to be some internal function to get that output somewhere.
 
 
Best,
