Render in 2 forms

Ok, so for my scene, I have a particle fog so create some volumetric lights, and if I render it using Vertex Lit rendering, it looks great. However, nothing else does. And if I render using deferred lighting, everything else looks great, but the particles look horrendous. Is there any way for me to set one camera to render the particles and overlay it onto the deferred lighting camera?

Will camera layers produce what you need?
