I did a very quick and crappy mock-up of what this could maybe look like:
"Overrides" should probably be renamed "Render Settings Overrides" or similar.
The wording and ordering is not good, but the idea is there. The mod is basically already there purely for overrides to your main render setup settings, so I don't see any reason why it can't contain more overrides than it already has (for cleanliness reasons I mean).
It could be separated into sections:
Section 1 - Lens-based Overrides (e.g. the top stuff like iso, SS, aperture etc.)
Section 2 - Exposure & Toning Overrides
Section 3 - Render overrides (e.g. dof/mb/passes/msi etc.).
Section 4 - Projection Type
